Synthesis and Crystal Structure of a 3D Supramolecular Copper(II) Complex With 1-(3-{[(E)-3-bromo-5-chloro-2-hydroxybenzylidene]amino}phenyl) ethanone Oxime.

A new Cu(II) complex, [Cu(L)2], has been synthesized via the complexation of copper(II) acetate monohydrate with a new oxime-type ligand (HL = 1-(3-{[(E)-3-bromo-5-chloro-2-hydroxybenzylidene]amino}phenyl)ethanone oxime). X-ray crystallographic analysis reveals that the complex is a mononuclear complex. The Cu(II) atom is four-coordinated by the phenolate O atoms and imine N atoms from two oxime-type ligands, in a square-planar geometry in which the dihedral angle of two coordination plane (Cu1N1O1 and Cu1N#1O#1) is 0°. The crystal packing of the Cu(II) complex shows that a notable feature of this structure resides in the formation of a novel 3D supramolecular networks through intermolecular O–H···N, C–H···O, and C–H···π interactions.
