Die (1-Cyclohepta-2,4,6-trienyl)thiolato-verbrüuckten Zweikernkomplexe – Mn2(CO)8(μ2-SC7H7)2 und Mn2(CO)6(C≡NtBu)2(μ2-SC7H7)2 / The (1-Cyclohepta-2,4,6-trienyl)thiolato-Bridged Dinuclear Complexes Mn2(CO)8(μ2-SC7H7)2 and Mn2(CO)6(C≡NtBu)2(μ2-SC7H7)2

Abstract

The reactions of either Mn2(CO)10 (under irradiation) or Mn(CO)5X (X = Cl, Br) with di(1-cyclohepta-2,4,6-trienyl) sulfide, S(C7H7)2 (1), led to the organothiolato-bridged dimer [Mn(CO)4(μ2-SC7H7)]2 (2) in addition to ditropyl, (C7H7)2. Subsequent substitution of two carbonyl ligands in 2 for tert-butyl isocyanide gave [Mn(CO)3(C≡NtBu)(μ2-SC7H7)]2 (3). The molecular structures of the centrosymmetric dimers 2 and 3 have been determined by X-Ray crystallography. Both 2 and 3 contain a planar Mn2S2 core with the 1-cyclohepta-2,4,6-trienyl substituents in anti-position. The structural parameters of dinuclear carbonylmanganese complexes containing organothiolato or thioether bridges are discussed.
