(2,2′-Bipyridine-κ2N,N′)bis­(5-thioxo-1,5-dihydro-1,3,4-thia­diazole-3-thiol­ato-κS)­zinc(II)

In the crystal structure of the title compound, [Zn(C2HN2S3)2(C10H8N2)], a twofold rotation axis passes through the Zn atom and the midpoint of the C—C bond linking the two pyridine rings. The ZnII atom is located on a 21 axis and is coordinated by two thiol­ate S atoms of different 5-thioxo-1,5-dihydro-1,3,4-thia­diazole-3-thiol­ate ligands and two N atoms of a 2,2′-bipyridine ligand in a tetra­hedral geometry, with a Zn—S distance of 2.3204 (8) A and a Zn—N distance of 2.061 (2) A. In addition, mononuclear mol­ecules are linked together to form a one-dimensional chain by N—H⋯S hydrogen bonds.
