Abstract
Reaction of the [Rh(eta(5)-C5Me5)(NCMe)(3)](2+) (1) dication with the hexaosmium [Os-6(CO)(17)](2-) (2) dianion leads to the initial formation of [Os-6(CO)(17) Rh(eta(5)-C5Me5)] (3). This cluster readily adds CO to form [Os-6(CO)(18)Rh(eta(5)-C5Me5)] (4) which has been characterised crystallographically. 3 also adds dihydrogen to give [Os6H2(CO)(17)Rh(eta(5)-C5Me5)] (5) and undergoes a substitution reaction with wPPh(3) to form [Os-6(CO)(16)(PPh3)Rh(eta(5)-C5Me5)] (6). With the [Ru-6(CO)(18)](2-) (7) dianion, [Rh(eta(5)-C5Me5)(NCMe)(3)](2+) (1) reacts to form three mixed-metal clusters [Ru-5(CO)(15)Rh(eta(5)-C5Me5)] (8), [Ru-6(CO)(18)Rh(eta(5)-C5Me5)] (9) and [Ru-6(CO)(18)Rh-2 (eta(5)-C5Me5)(2)] (10). The clusters have been characterised spectroscopically and the structures of 8 and 10 have been confirmed crystallographically. The cluster 8 undergoes a substitution reaction with P(OMe)(3) to form the disubstituted product [Ru-5(CO)(13)(P(OMe)(3))(2)Rh((eta(5)-C5Me5)] (11) which has also been characterised crystal lographically.
