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-N 2,N 2’-(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.
