Characterization, luminescent properties, and crystal structure determination of [Pt(Ph2bipy)Cl2]

详细

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.
