Abstract

The title compound, {[Cd(NCS)2(CH4N2S)2]·2H2O}n, forms a one-dimensional chain parallel to the a axis, caused by the presence of the bridging thiocyanate groups. Two solvent molecules per complex are present in the lattice. The CdII ion is situated on an inversion centre and is coordinated in a distorted octahedral fashion by two N and two S atoms from four thiocyanate ligands and by two S atoms from two thiourea molecules. Weak O—H...S, N—H...O and N—H...N interactions reinforce the structure.
