New Mixed‐Metal Carbonyl Complexes Containing Bridging 2‐Mercapto‐1‐methylimidazole Ligand

Abstract Reaction of [Mn 2 (CO) 10 ] with 2‐mercapto‐1‐methylimidazole in the presence of Me 3 NO at 25 °C afforded two new dimanganese complexes [Mn 2 (CO) 6 ( μ ‐SN 2 C 4 H 5 ) 2 ] ( 1 ) and [Mn 2 (CO) 7 ( μ ‐SN 2 C 4 H 5 ) 2 ] ( 2 ). Compound 1 consists of two μ ‐SN 2 C 4 H 5 ligands, each bound through the sulfur atom to two Mn atoms and through the nitrogen atom to one Mn atom forming a four‐membered chelate ring. Compound 2 was found to consist of one μ ‐SN 2 C 4 H 5 ligand in a similar bonding mode…
