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

The Cu(II) atom in the title complex, [Cu(C(19)H(17)N(5)O(5))], 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.
