NON-CHEMICAL NETWORKS

There are also non-chemical networks that have structures, that do not correspond to any known type of chemical bonding genre...there may in fact be more of these non-chemical networks, than there are networks that correspond to chemistry...an example of a non-chemical network type is any pattern that involves a 3-3 bond that is staggered and not eclipsed...in such a motif the p-orbitals of the ordinary pi bond are perpendicular to each other making a pi bond formation impossible...Wells, in his great work, "Three Dimensional Nets and Polyhedra", shows a photograph of at least one such non-chemical network, which is just a 3-,4-connected pattern in uniform 8-gon circuits...in addition there may be some Andreini or non-Andreini space fillings of polyhedra that can be transformed over to non-chemical networks, including those with vertices which, in-plane, connect to more than 6 other points...like an 8-fold coordinated in-plane vertex, translated over from an octagonal parallelohedron, within some Andreini, or perhaps, non-Andreini space filling of polyhedra, for example...such space fillings would not have any chemical analogue and they may be more numerous than other space fillings of polyhedra with chemical analogues..
