title: Aqua-bis-[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole-κ(2)N(2),N(3)](trifluoro-methane-sulfonato-κO)copper(II) trifluoro-methane-sulfonate.
abstract: 2,5-Bis(pyridin-2-yl)-1,3,4-thia-diazole (denoted L) has been found to act as a bidentate ligand in the monomeric title complex, [Cu(CF(3)O(3)S)(C(12)H(8)N(4)S)(2)(H(2)O)](CF(3)O(3)S). The complex shows a distorted octahedrally coordinated copper(II) cation which is linked to two thia-diazole ligands, one water mol-ecule and one trifluoro-methane-sulfonate anion. The second trifluoro-methane-sulfonate anion does not coordinate the copper(II) cation. Each thia-diazole ligand uses one pyridyl and one thia-diazole N atom for the coordination of copper. The N atom of the second non-coordinating pyridyl substituent is found on the same side of the 1,3,4-thia-diazole ring as the S atom. The trifluoro-methane-sulfonate ions are involved in a three-dimensional network of O-H⋯O hydrogen bonds. C-H⋯N inter-actions also occur.
