 Title    Zweikernige Mangan-und Rheniumkomplexe mit gemischt aliphatischen-aromatischen Kohlenwasserstoffbrücken Dinuclear Manganese and Rhenium Complexes with Mixed Aliphatic-Aromatic Hydrocarbon Bridges  
 Abstract    The symmetrically hydrocarbon-bridged complexes (OC)5M -(C H 2)n+1-X -(C H 2)n+|-M (CO)5 [n = 1, X = 1,4-C6H4, M = Mn (2a), M = Re (3a); n = 2, X = 1,4-C6H4, M = Mn (2b), M = Re (3b); n = 1, X = 1,3-C6H4, M = Mn (5a), M = Re (6a); n = 2, X = 1,3-C6H4, M = Mn (5b), M = Re (6b); n = 1, X = 1,2-C6H4, M = Mn (8a), M = Re (9a); n = 2, X = 1,2-C 6H4, M = Mn (8 b), M = Re (9b)] are obtained by the reaction of the bistriflates X[(CH2)"-C H 2-0 S 0 2CF3]2 [X = 1,4-C6H4, n = 1 (la), n = 2 (lb); X = 1,3-C6H4, n = 1 (4a), n = 2 (4b); X = 1,2-C6H4, n = 1 (7 a), n = 2 (7 b)] with the carbonyl metalates [M(CO)5]" (M = Mn, Re) in THF and dimethyl ether, respectively. According to an X-ray structural analysis 8a crystallizes in the triclinic space group PI with Z = 2. Depending on the solvent, the reaction of 7 a with [Mn(CO)5]" affords also the cyclic carbene complex 10 a. The behavior of the manganese compounds toward CO has been investigated exemplarily in the case of 8 a and leads to the diacyl complex l,2-C6H4[CH2CH2C (0)M n(C 0)5]2 (11). Upon reaction with Na2C 0 3/CH30 H 11 is con­ verted to give the corresponding diester 1,2-C6H4[CH2CH2C (0)0 C H 3]2 (12).
