Abstract: The title complex, {[CdHg(SCN)₄(H₂O)]·C₄H₈O₂S}_n, comprises slightly distorted CdN₄O₂ octahedra and HgS₄ tetrahedra where the donor atoms are derived from ambidentate thiocyanate ligands and, in the case of cadmium, also from water molecules. Pairs of Cd atoms are bridged by two water molecules, forming a parallelogram, and each water molecule is hydrogen bonded to a sulfolane molecule. Pairs of Cd and Hg atoms are connected by -SCN- bridges, which leads to the formation of a three-dimensional -Cd-NCS-Hg- network.
