The geometrical basis of crystal chemistry. Part 2

Abstract

A procedure for the systematic derivation of 3-dimensional 4-connected nets is outlined and applied to nets with 2, 3, and 4 points in the repeat unit. The relevance to crystal chemistry of nets contg. loops (digons) is noted. Some of the simplest open packings of tetrahedra are indicated, and a no. of more complex nets (4-, 5-, 6-, 8-, and 12-connected) with cubic symmetry are listed. [on SciFinder(R)]
