Aqua­bis­[2,5-bis­(pyridin-2-yl)-1,3,4-thia­diazole-κ(2) N (2),N (3)](trifluoro­methane­sulfonato-κO)copper(II) trifluoro­methane­sulfonate

2,5-Bis(pyridin-2-yl)-1,3,4-thia­diazole (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 thia­diazole ligands, one water mol­ecule and one trifluoro­methane­sulfonate anion. The second trifluoro­methane­sulfonate anion does not coordinate the copper(II) cation. Each thia­diazole ligand uses one pyridyl and one thia­diazole 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-thia­diazole ring as the S atom. The trifluoro­methane­sulfonate ions are involved in a three-dimensional network of O—H⋯O hydrogen bonds. C—H⋯N inter­actions also occur.
