Bis[μ-(E)-N′-(4-oxido-4-phenylbut-3-en-2-ylidene)benzohydrazidato]bis[pyridinecopper(II)]

In the crystal structure of the title centrosymmetric dimer, [Cu2(C17H14N2O2)2(C5H5N)2], the CuII atom has an almost perfect square-pyramidal geometry. The CuII ion is coordinated by the NO2 donor atoms of the hydrazide Schiff base ligand, the N atom of the pyridine group and an O atom of the symmetry-related unit. The dihedral angles between the pyridine ring and the two phenyl rings of the ligand are 21.4 (3) and 24.0 (2)°. The molecular structure is stabilized by intramolecular C—H...O interactions
