| Abstract: | Novel binuclear substituted manganese(I) carbonyls Mn(CO)4?nLn]2(μ-N-N)2 (n = 1, (N-N)2 = biimidazolate, L = PBun3; (N-N)2 = bibenzimidazolate, L = P(OMe)3, P(OPh)3, PPh3, PEt3 or PBun3, as well as n = 2; (N-N)2 = biimidazolate, or bibenzimidazolate, L = PBun3, PEt3 or P(OMe)3) are described, in which the anions (N-N)2 act as tetradentate bridging-groups. They were prepared by treating Mn(CO)4(μ-Br)]2 with thallium or potassium salts of 2,2′-biimidazole or 2,2′-bibenzimidazole and subsequent displacement of CO by L. The structures of the complexes are discussed. |
