title: Bis{μ-4-chloro-N'-[(E)-1-(5-chloro-2-oxidophen-yl)ethyl-idene]benzohydrazidato}bis-[pyridine-copper(II)].
abstract: The crystal structure of the title complex, [Cu(2)(C(15)H(10)Cl(2)N(2)O(2))(2)(C(5)H(5)N)(2)], features centrosymmetric dimers. The Cu(II) ion is penta-coordinated in a quadratic pyramidal mode. The quadratic plane is formed by the O,O',N-tridentate ligand and a pyridine mol-ecule. The fifth coordination site is occupied by the O atom of another ligand showing a significantly longer Cu-O bond.
