Poly[[μ-aqua-tetra-μ-thio­cyanato-cadmium(II)mercury(II)] sulfolane solvate].

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. [ABSTRACT FROM AUTHOR]
