catena-Poly[[bis­(2-meth­oxy­aniline-κN)cadmium]-di-μ-thio­cyanato-κ²N:S;κ²S:N]

The structure of the title compound, [Cd(NCS)₂(C₇H₉NO)₂]_n, consists of cadmium–thio­cyanate layers parallel to the ab plane. Pairs of Cd^II ions are bridged by two end-to-end inversely bridging μ-NCS-N:S thio­cyanate groups, forming a two-dimensional network with the remaining two trans positions of the octa­hedrally coordinated Cd^II ions occupied by the N atoms of two neutral 2-meth­oxy­aniline ligands. The crystal structure is stabilized by intra­layer N—H...S hydrogen bonds.

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.
