| Abstract: A Schiff base chelating ligand containing oxime group, 1-(4-{[(E)-5-chloro-2-hydroxybenzylidene]amino}phenyl)ethanone O-benzyloxime (HL, C15H16N2O) and its Cu(Ⅱ) complex ([CuL2]) have been synthesized and characterized by elemental analyses, IR spectra, UV-Vis spectra and X-ray single crystal diffraction method. In the crystal structure of HL, the intermolecular Cl…Cl halogen bonding interaction links a pair of HL molecules to form a dimer unit with the Cl…Cl distance of 0.3459(3) nm, and every dimer further links four other adjacent dimer units into an infinite 3D supramolecular networks structure containing 1D rectangle channels by intermolecular C-H…π interactions. The structure of the Cu(Ⅱ) complex is a mononuclear, consists of one Cu(Ⅱ) atoms, two bidentate L- units. The Cu(Ⅱ) atom is in a square-planar geometry. And each Cu(Ⅱ) complex molecule links four other molecules into an infinite 2D layer supramolecular structure by intermolecular C-H…π interactions. This linkage is further stabilized by π…π stacking interactions with the centroid-centroid distances of 0.3689(3) nm. |
