Table of known examples
Attempts to synthesise polymeric networks with porous structures often result in the formation of interpenetrating networks. These networks have no chemical bonds connecting them and yet cannot be separated without breaking of bonds. They can be considered to be polymeric analogues of rotaxanes and catenanes. The links above are to a comprehensive table of all known examples.
Information of a more general nature is given below.
Entanglement of polymeric networks such that, although there is no direct connection between the networks, they cannot be separated (in a topological sense) without requiring the breaking of network connections.
This is highlighted by the two examples below which are not interpenetrating. The individual networks could theoretically be separated without breaking bonds.
The chains, although entangled like threads in cloth, can be separated without breaking them.
The sheets are interdigitating not interpenetrating.
The networks must also interpenetrate each other in a mutual fashion - i.e. each network must be penetrated by another. Again, the example below, which shows 1D linear chains within channels created by the stacking of 2D nets, is not interpenetrating because the 1D chains are not penetrated by the 2D
This system is not interpenetrating.
To properly describe a structure with interpenetrating networks, one must describe not only the topology of the individual networks, but also the topology of interpenetration, i.e. the way the networks interpenetrate each other. We have developed a descriptive nomenclature to assist with this.
The first consideration is the dimensionality of the individual nets - 1D, 2D or 3D. If the nets are 1D or 2D, then there are two possibilities. For 1D nets, the mean directions of propogation of the nets can be either parallel or inclined. Similarly, for 2D nets the mean planes of the nets can also be either parallel or inclined.
The next consideration is whether the overall dimension of the entanglement is the same as the constituent nets or higher. For example, parallel interpenetration of 1D nets can lead to overall 1D, 2D or 3D entanglements. In contrast, however, inclined interpenetration of 2D nets can only lead to a 3D entanglement.
These considerations are drawn together in the following notation:
mD → nD parallel/inclined interpenetration
For networks which involve interpenetration between networks of different dimensions (see below), then mD is replaced by mD/pD. For interpenetrating nets which have the same dimensionality but different topology (also see below), mD is replaced by mD/mD. For 2D inclined interpenetration, only a 3D entanglement is possible, so the → 3D is redundant and omitted. Similarly, for 3D interpenetration, everything from the arrow onwards in the nomenclature is redundant and omitted.
The links below illustrate the different types of interpenetration possible.
- Interpenetration of 1D nets
- Interpenetration of 2D nets
- Borromean interpenetration
- Interpenetration of 3D nets
- Interpenetration of nets of different dimensions
- Interpenetration of nets of different topology
- Interpenetration of 0D nets (polycatenanes)
The above nomenclature is a useful but often not sufficient description of the topology of interpenetration. For example, the four schematic diagrams below all show 2D → 2D parallel interpenetration of (4,4) nets, however the interpenetration topologies are all different.
Four different topologies of interpenetration.
Similarly, 3D nets can interpenetrate with different topologies. For example, below are two different ways in which two alpha-Po networks can interpenetrate. In the left example, the "normal" mode of interpenetration, each cubic cavity catenates with eight such cavities of the other net. In the example on the right, an "abnormal" mode, a cavity of one net catenates with ten cavities of the other net. Diamond is another 3D topology which commonly shows a normal mode of interpenetration, with a minority of structures which show abnormal modes.
Normal mode of interpenetration.
Abnormal mode of interpenetration.

The main technique we use to determine the 3D molecular structures of our compounds is X-ray Crystallography, using the two area-detector diffractometers in the School of Chemistry, the MX1 and MX2 beamlines at the Australian Synchrotron, and the Koala beamline at the ANSTO nuclear reactor. By measuring the diffraction patterns formed from an X-ray (or neutron) beam passing through a crystal of our product, we can determine its precise molecular structure.

The aim of crystal engineering is to control the way molecules assemble in the solid state. Since the properties of any material are largely due to its structure, control over the structure allows us to manipulate these properties. The crystal engineering of coordination polymers is of particular interest to our group. By judicious choice of preferred ligand and metal coordination geometries, control over the topology and geometry of the infinite networks can be gained. Such control allows the deliberate design of materials with a range of useful properties, including electronic properties, magnetic properties (long-range magnetic ordering, spin-crossover materials), microporosity (including the related properties of ion exchange and heterogeneous catalysis), non-linear optical effects and luminescent properties. We are currently developing a number of approaches to such materials. Specific aims include new materials for storage of hydrogen (with applications in e.g. hydrogen fuelled transportation) and the capture of carbon dioxide (for pollution control).

In conjunction with Prof. Keith Murray, we have been studying the structures and magnetism of the coordination polymers of small nitrile anions, such as dicyanamide (dca, N(CN)2-) and tricyanomethanide (tcm, C(CN)3-). We have discovered a new class of magnetically ordering compounds that has sparked a surge in interest in dca coordination polymers. The α-[M(dca)2] compounds all have rutile-like structures in which octahedral metal centres are bridged by three-connecting dca ligands (which coordinate through all three nitrogen atoms). Despite their isomorphous structures, the magnetic properties vary widely: Cr, Mn and Fe are spin-canted antiferromagnets (TN = 47, 16, 19 K), Co, Ni and Cu are ferromagnets (Tc = 9, 21, 1.7 K). The ß-[M(dca)2] phase is formed by tetrahedral metals, and is composed of (4,4) 2D sheets of metals bridged by μ2 ligands (the amide nitrogen does not coordinate). The effect of structure on magnetic properties is illustrated by the fact that both phases can be isolated for M = Co, however while the α phase is a ferromagnet, the ß phase is a spin-canted antiferromagnet (TN = 9 K). The dimensionality of the dicyanamide coordination polymers can also be reduced by the introduction of terminal solvent ligands such as H2O, MeOH, EtOH, DMF and pyridine. An unusual tube-like 1D polymer is formed when 2-aminopyridine is added to the reaction mixture; the topology of the tube is identical to the square channels in the α-[M(dca)2] rutile-like networks.
Polymorphism and pseudo-polymorphism is common in dca coordination polymers. In addition to the α and ß forms of [M(dca)2], α-[Cu(dca)2(pyz)] contains two interpenetrating α-Po-like 3D networks, while the ß form contains 2D (4,4) sheets. Two compounds are isolated from a reaction mixture containing Cu(I), dca and 4,4'-bipyridine whose formulae differ only by the number of solvent molecules in the structure; one contains 1D ladder-like polymers while the other has a thick 2D layer structure. This latter compound displays 2D parallel interpenetration, with each layer interlocked with four others. The mean planes of the layers, however, are parallel but not coincident, and thus the interlocking generates an overall 3D structure rather than the usual formation of 2D layers. Cu(dca)(bpe), bpe = 1,2-bis(4-pyridyl)ethene also has an α phase (twofold parallel interpenetration of (4,4) 2D sheets) and a ß phase (five interpenetrating diamond like nets in which the topology of interpenetration is unprecedented).
More recently we have been studying, in collaboration with Prof. Murray, Prof. Glen Deacon and Dr. David Turner, the chemistry of other related anions, and in particular dicyanonitrosomethanide (dcnm, C(CN)2(NO)-). This anion has been found to undergo nucleophilic addition of water, alcohols, and amines across one or both of the nitrile groups, to generate new families of anions. These anions have been used in a remarkable array of applications, including synthesis of new organic anions and ligands, coordination polymers of interest for long-range magnetic ordering and gas sorption, metal clusters which may act as single molecule magnets, new hydrogen bonded materials, new homoleptic lanthanoid complexes, and as anions for novel ionic liquids (as both the free anion and as anionic [LnL6]3- complexes). We have been investigating the formation and properties of these ionic liquids in collaboration with Prof. Doug MacFarlane (free anions) and Prof. Anja-Verena Mudring (Ln complexes), and have also undertaken theoretical studies on the chemistry of the anions with Dr. Ekaterina Izgorodina.
