Periodic nets and tilings: possibilities for analysis and design of porous materials
Ever since crystal structures were first determined, it has been realized that their underlying topologies are conveniently described in terms of periodic nets. Nets are topological structures that are special sorts of graphs. For definitions and the applicability of aspects graph theory to crystal nets we refer the reader to a recent review 1. It was natural to ask what were the principal possibilities for nets and efforts, most notably by A. F. Wells 2,3, were made to systematically enumerate such structures, although in practice the methods used were essentially empirical. The rising importance of zeolites for practical applications spurred attempts to prepare new materials and in this connection special attention was devoted to enumerating nets with all 4-valent vertices (often called 4-connected but we prefer 4-coordinated 1). In this last effort special mention should be made of the work of J. V. Smith and collaborators 4,5. Again, this work, although systematic, proceeded empirically.
