Hydrocarbon-Bridged Complexes, XXV. - C-C Coupling of Anionic Tricarbonyl Manganese Complexes of Cyclic Polyenes with Cationic Tropylium Metal Compounds; Preparation and Structure of (OC)3Mn(-5:6-C7H8-C7H7)M(CO)3, (OC)3Mn(-5:6-C8H10-C7H7)M(CO)3, and (OC)3Mn(-5:5-C8H8-C7H7)M(CO)3 (M = Cr, Mo, W)[Note ]

The addition of the anionic complexes [(4-C7H8)Mn(CO)3]-, [(4-C8H10)Mn(CO)3]- and [(4-C8H8)Mn(CO)3]- to the cations [(7-C7H7)M(CO)3]+ (M = Cr, Mo, W) gives the hydrocarbon-bridged complexes (OC)3Mn(-5:6-C7H8-C7H7)M(CO)3, (OC)3Mn(-5:6-C8H10-C7H7)M(CO)3, and (OC)3Mn(-5:6-C8H8-C7H7)M(CO)3 (M = Cr, Mo, W). The structures of 4b and 6a have been determined by X-ray diffraction.
