Topological systematization of layered coordination compounds of Cu, Ag, Zn, and Cd

Abstract

The topological analysis and systematization of basis lattices in 1972 coordination compounds of Cu, Ag, Cd, and Zn containing organic ligands and layered complex groups (both isolated and interlaced with each other) are carried out by the TOPOS structural topological program package. The structures considered are most frequently based on the square (sql) or hexagonal (hcb) Shubnikov lattice (38.6 and 18.7%, respectively). The increased specificity of the sql and hcb lattices is due to specific features of coordination of the lattices facilitating their mutual penetration. Two types of interlacing of the layered groups (parallel and inclined) are revealed, and the former predominates.
