Crystal structure of dichlorido-(6-methyl-1H-benzo[d]imidazole-2-thiolo κS)-(triphenylphosphine-κP)palladium(II)-methanol monosolvate (1:1), [PdCl2(C8H8N2S)(C18H15P)]·CH3OH, C27H27Cl2N2OPPdS

Abstract

Source of materialA mixture of PdCl 2 (0.2mmol) and 6-methyl-1H-benzo[d]-imidazole-2-thiole (mbitH) (0.2 mmol) in MeOH and CH 2 Cl 2 (10mL, v/v = 1:1) was stirred for 2h and then PPh 3 (0.2mmol) was added to the mixture which was stirred for another 4h. The insoluble residues were removed by filtration, and the filtrate was evaporated slowly at room temperature for a week to yield red, crystalline products. DiscussionThe chemistry of palladium(II) complexes is of considerable interest due to their potential applications in organic synthesis, catalysis and photo-physical chemistry [1][2][3]. The ligand mbitH molecule, with one -SH and two potential coordination nitrogen atoms, is excellent in building supramolecular structures [4,5]. However, to our best knowledge, the palladium(II) complex with mbit has not been reported. In the title complex, Pd atom is coor-
