✦ Synopsis

The title polymeric compound, {[MnHg(SCN) 4 (H 2 O)]Á-C 4 H 8 O 2 S} n , consists of slightly distorted MnN 4 O 2 octahedra and HgS 4 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 threedimensional structure.
