Characterization, crystal structure determination, and luminescent properties of [Pd(4,4′-bit)Cl2]

Abstract

Complex [Pd(4,4′-bit)Cl₂] (1) is synthesized by the reaction of PdCl₂ and 4,4′-bithiazole (4,4′-bit) in acetonitrile and crystallized by vapor diffusion of methanol into a dimethyl sulfoxide solution of the complex. This complex is thoroughly 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. The X-ray structure determination shows that in the structure of this complex, the Pd(II) atom is fourcoordinated in a slightly distorted square-planar configuration by two nitrogen atoms from a bidentate 4,4′-bithiazole ligand and two chloride ions.
