Synthesis, crystal structure, and catalytic properties of 2,2’-bipyridyl-dicyano-palladium(II)

Abstract

In the solvothermal condition, a Pd(II) complex with a in situ synthesis ligand, [Pd(2,2’-bipy)2(CN)2] (1) was obtained and characterized by elemental analysis, IR, UV, TG, and powder X-ray analysis. The single crystal X-ray analysis showed that the title complex is different from the reported 2,2’-bipyridyldicyano-palladium(II) (2) in crystal system and structural parameters. The catalytic investigation for the reactions of the disproportionation of hydrogen peroxide and oxidation of sulfide showed that the complex 1 is an active homogeneous catalyst in the presence of imidazole and 2-sulfobenzoic acid, respectively.
