[μ-4-Benzoyl-1-(1-oxido-2-naphthylcarbonyl)thiosemicarbazidato(4−)]bis[pyridinecopper(II)]

Abstract

In the title dinuclear complex, [Cu2(C19H11N3O3S)(C5H5N)2], the two CuII centers have different coordination environments, viz. N2OS and N2O2, each exhibiting a distorted square-planar geometry. π–π interactions between the aromatic rings of neighbouring complexes [centroid–centroid distance = 3.856 (5) Å] link pairs of molecules into centrosymmetric dimers, which are further packed into stacks along the b axis with relatively short Cu...Cu separations of 3.482 (1) Å. Weak intermolecular C—H...N hydrogen bonds help to consolidate the crystal packing.
