The addition of Re(CO)5-, Mn(CO)5-, and 5-C5H5)W(CO)3>- to the cationic dienyl complexes 5-dienyl)M(CO)3>+ (M = Fe, Ru; dienyl = hexadienyl, cyclohexadienyl, cycloheptadienyl, cyclooctadienyl, bicyclooctadienyl) gives the heterobimetallic η1:η4-hydrocarbon-bridged complexes 1-4, 6, 7.In solution the initial nucleophilic adduct 2e of 5-cycclohexadienyl)Ru(CO)3>+ and - rearranges to the complex 3, in which the Re(CO)5 group is bound to a sp2 carbon atom.By using Mn(CO)5- also the products of electron transfer between cation and anion have been observed.The crystal structures of (OC)3Fe(μ-η4:η1-hexadiene)Re(CO)5 (1), (OC)3Ru(μ-η4:η1-cyclohexadiene)Re(CO)5 (3), (OC)3Fe(η4:η4-C7H9-C7H9)Fe(CO)3 (5), (OC)3Ru(μ-η4:η1-cyclooctadiene)Re-(CO)5 (6b), and of (OC)3Fe(η4:η1-bicyclooctadiene)-Re(CO)5 (7) have been determined by X-ray diffraction.Key Words: Heterobimetalic complexes / Tungsten complexes / Iron complexes / Ruthenium complexes / Manganese complexes / Rhenium complexes / Diene bridges, ?,?-C6, -C7, and -C8
