[2,2′-Dihydroxy-N2,N2′-(3-hydroxyiminopentane-2,4-diyl)dibenzohydrazidato]copper(II)

Abstract

The CuII atom in the title complex, [Cu(C19H17N5O5)], is coordinated by two N atoms and two O atoms of one 2,2′-dihydroxy-N2,N2'-(3-hydroxyiminopentane-2,4-diyl)dibenzohydrazidate ligand, exhibiting a distorted square-planar geometry. The dihedral angle between the two benzene rings in the oxime hydrazone is 7.62 (15)°. The molecular configuration is stabilized by intramolecular O—H...N hydrogen bonds. Pairs of centrosymmetrically related molecules are linked into dimers by two intermolecular C—H...O hydrogen bonds. Each dimer is further connected to four neighboring dimers via four O—H...O hydrogen bonds, forming an extended two-dimensional structure. The oxime O atom is disordered over two orientations in a 2:1 ratio.
