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

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 Cd^II 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.
