Syntheses and X-ray structures of heteroleptic octahedral Mn(II)-xanthato complexes involving N-donor ligands

Abstract

A series of octahedral manganese(II) complexes involving xanthates and N-donor ligands, [Mn(S2COiBu)2(phen)] (1), [Mn(S2COiBu)2(2,2′-bpy)] (2), [Mn(S2COnPr)2(phen)] (3), [Mn(S2COnPr)2(2,2′-bpy)] (4), [Mn(S2COMe)2(2,2′-bpy)] (5), [Mn(S2COnPr)2(4,4′-bpy)]n, and [Mn2(S2COnPr)4(4,4′-bpy)3] (6) (phen = 1,10-phenanthroline, bpy = bipyridine) was prepared. Complexes were characterized by elemental analysis, FTIR spectroscopy, TG/DSC analysis, and single-crystal X-ray diffraction. The structures are built of monomeric molecules of the complexes, except for 6 with the 4,4′-bipyridine ligand, which contains a binuclear complex and 1D polymeric zigzag chain in one crystal.
