Di-μ-chlorido-bis-{aqua-chlorido[2,2'-thio-bis(pyridine N-oxide)-κO]copper(II)}.

The crystal structure of the title compound, [Cu(2)Cl(4)(C(10)H(8)N(2)O(2)S)(2)(H(2)O)(2)], comprises neutral centrosymmetric μ-chloride-bridged dinuclear units. Each Cu(II) ion is penta-coordinated by three chloride ligands, a pyridine N-oxide O atom and a water mol-ecule. Intra- and inter-molecular O-H⋯O hydrogen bonds occur between the coordinated water mol-ecules and the uncoordinated and coordinated pyridine N-oxide groups of the 2,2'-thio-bis(pyridine N-oxide) ligands, respectively.
