Abstract
The Me3NO initiated reaction between Mn2(CO)10 and 2-mercaptobenzimidazole (mbiH) at room temperature leads to the formation of dinuclear Mn2(CO)6(µ-κ2-mbi)2 (1) in which the metal atoms are linked by the sulfur atoms of the heterocyclic ligands. Complex 1 reacts with triphenylphosphine (PPh3), bis(diphenylphosphino)methane (dppm) and 1,2-bis(diphenylphosphino)ethane (dppe) at room temperature to afford mononuclear Mn(CO)3(PPh3)(κ2-mbi) (2), Mn(CO)3(κ2-dppm)(κ1-mbi) (3) and Mn(CO)3(κ2-dppe)(κ1-mbi) (4), respectively, via metal-sulfur bond scission. Upon gentle heating, 1 also reacts with Os3(CO)10(NCMe)2 and Ru3(CO)12 to yield the mixed-metal clusters MnOs3(CO)13(μ3-κ2-mbi) (5) and MnRu3(CO)13(μ3-κ2-mbi) (6), respectively, which contain a Mn(CO)3(mbi) fragment. All these new complexes have been characterized by analytical and spectroscopic data, together with single crystal X-ray diffraction analyses for 1, 3, 4 and 5.
