Synthesis, crystal-molecular structure and spectral investigation of mixed-ligand Cu(II) new complex with 1,10-phenanthroline bidentate ligand by Salicylaldehyde S-benzylisothiosemicarbazone

Mixed-ligand Cu(II) complex was prepared by reaction of salicylaldehyde S-benzylisothiosemicarbazone hydrogenchloride ligand (H2L), Cu(ACo)2.H2O and 1,10-phenanthroline with general formulas [Cu(Phen)2Cl].H2L,Cl,H2O. Its structure was fully characterized by elemental analysis and IR method and single crystal diffraction was also used to better understanding of the molecular structure of the Cu(II) complex. In the Cu(II) complex, coordination geometry around the central atom is a distorted square-pyramidal. Two 1,10-phenanthroline ligands (NN donor) are coordinated to the central metal as a neutral bidentate agent. Another position of the square-pyramidal geometry is occupied by the chlorine atom.
