{(E)-4-Hydroxy-N′-[phenyl(pyridin-2-yl-κN)methylidene]benzohydrazide-κ2N′,O}bis(nitrato-κ2O,O′)copper(II)

Abstract

In the title compound, [Cu(NO3)2(C19H15N3O2)], the coordination geometry around the CuII ion can be described as distorted square-pyramidal, with two N atoms and one O atom from an (E)-4-hydroxy-N′-[phenyl(pyridin-2-yl)methylene]benzohydrazide ligand and one nitrate O atom in the basal plane and one nitrate O atom at the apical site. The other two nitrate O atoms also bind to the Cu atom with long Cu—O distances [2.607 (4) and 2.853 (5) Å]. The crystal packing is stabilized by intermolecular N—H...O and O—H...O hydrogen bonds.
