Abstract
New complex [Pt(Ph2bipy)Cl2] (1) is obtained from the reaction of H2PtCl6×6H2O and 4,4¢-diphenyl-2,2¢-bipyridine (Ph2bipy) in a mixture of methanol, chloroform, and dimethyl sulfoxide. Suitable crystals of 1 for the diffraction experiment are obtained by slow evaporation of the resulted orange solution at room temperature. This complex is characterized by elemental analysis, IR, 1H NMR, UV-Vis, and luminescence spectroscopy and its structure is studied by the single crystal X-ray diffraction method. X-ray structure determination shows that in the structure of this compound, the Pt(II) atom is four-coordinated in a distorted square-planar configuration by two nitrogen atoms from a bidentate 4,4¢-diphenyl-2,2¢-bipyridine ligand and two terminal chlorine atoms.
