Abstract

A new Cu(II) complex, [CuL2(H2O)2]·H2O (HL = N-nicotinoylglycine), has been obtained using N-nicotinoylglycine, copper(II) acetate monohydrate and NaOH as raw materials. The structure of the Cu(II) complex was characterized by elemental analysis and single crystal X-ray diffraction analysis. The Cu(II) ion is six-coordinated with two N atoms from two pyridine groups of L ligand and four O atoms of four coordinated H2O molecules. The Cu(II) complex forms a 2D layered structure and 3D network structure by the interaction of O-H···O hydrogen bonds. The catalytic activities of the Cu(II) complex catalyst for benzyl alcohol oxidation were determined with molecular oxygen as oxidant.
