| Abstract
| - Thiophene and selenophene derivatives of theruthenium hexamethylbenzene dication have been synthesized, and their reaction with [(1-methylnaphthalene)Mn(CO)3]BF4 (2) and Cp2Co was studied. Treatment of[(η5-C4R4S)Ru(η6-C6Me6)]2+ (1) with cobaltocene and[(1-methylnaphthalene)Mn(CO)3]BF4 (2) in CH2Cl2 at−78 °C led to the isolation of trimetallic (Mn2Ru)thiophene complexes (η6-C6Me6)Ru(SC4R4)Mn2(CO)6 (3).Similar treatment of the selenophene complex [(η5-C4H4Se)Ru(η6-C6Me6)]2+ gave the trimetallic (Mn2Ru) selenophene complex (η6-C6Me6)Ru(SeC4R4)Mn2(CO)6 (9).The X-ray structures of 3 and 9 show manganeseinserted into a C−S or C−Se bond and two metal−metalbonds with no bridging carbonyls.
- The trinuclear (Ru2Mn) clusters containing the open-chain ligands CR1CHCR3CR2X (X = Se, Te) are formed by the reaction of [(η5-C4HR1R2R3X)Ru(η6-C6Me6)]2+ (X = S, Se) with cobaltocene and [(1-methylnaphthalene)Mn(CO)3]BF4 in CH2Cl2 at −78 °C.
