[μ-1,4-Bis(1,2,4-triazol-1-ylmeth-yl)benzene]-bis-[aqua-(pyridine-2,6-dicarboxyl-ato)copper(II)] monohydrate

The title compound, [Cu(2)(C(7)H(3)NO(4))(2)(C(12)H(12)N(6))(H(2)O)(2)]·H(2)O, displays a discrete dinuclear structure, in which the central Cu(II) atom is five-coordinated in a distorted square-based pyramidal coordination geometry and the flexible ligand 1,4-bis-(1,2,4-triazol-1-ylmeth-yl)benzene adopts a bis-monodentate bridging mode linking the Cu(II) atoms. It is further assembled by O-H⋯O hydrogen-bond inter-actions involving both the coordinated and uncoordinated water molecules. The latter exhibits half-occupancy.
