title: [2,2'-Dihy-droxy-N,N-(3-hy-droxy-imino-pentane-2,4-di-yl)dibenzo-hydra-zid-ato]copper(II).
abstract: 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'-dihy-droxy-N(2),N(2)'-(3-hy-droxy-imino-pentane-2,4-di-yl)dibenzo-hydrazidate 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 inter-molecular 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.
