Abstract: The title polymeric compound, {[MnHg(SCN)₄(H₂O)]·C₄H₈O₂S}_n, consists of slightly distorted MnN₄O₂ octahedra and HgS₄ tetrahedra. Each Mn^II ion is bound to N atoms belonging to the thiocyanate (SCN) groups and to two O atoms of adjacent water ligands. The sulfolane molecule connects with the coordinated water molecule through hydrogen bonding. Each Hg^II atom is coordinated by four SCN S atoms. The two adjacent Mn^II atoms and two O atoms of bridging water molecules connect with one another and form a parallelogram. Each pair of Mn^II and Hg^II atoms is connected by an -SCN- bridge, forming an infinite three-dimensional structure.
