Poly[bis(μ2-1,3-phenylenediamine-κ2N:N′)di-μ-thiocyanato-κ2N:S;κ2S:N-cadmium]

Abstract

The structure of the title polymeric compound, [Cd(SCN)2(C6H8N2)2]n, exhibits a two-dimensional staircase-like structure parallel to (010) in which the CdII atom lies on a twofold rotation axis and has a distorted octahedral CdS2N4 geometry involving four μ-1,3-(SCN) group donors and two N-atom donors from 1,3-phenylenediamine ligands, which also have twofold symmetry. The major contributions to the cohesion and the stability of this two-dimensional polymeric structure are the covalent Cd—S,N bonds and one weak intralayer N—H...S hydrogen bond.
