Abstract

Reactions between the activated cluster [Os3(CO)10(NCMe)2] and malonic acid, succinic acid and dicarboxylic acetylene, respectively, lead to the formation of the linked cluster complexes [{Os3H(CO)10}2(CO2CH2CO2)] (1), [{Os3H(CO)10}2(CO2C2H4CO2)] (2), and [{Os3H(CO)10}2(C4O4)] (3) in good yield. Cluster 3 was subsequently treated with [Co2(CO)8] and this results in the addition of a "Co2(CO)6" group giving [{Os3H(CO)10}2(C2O4){Co2(CO)6}] (4). The X-ray crystal structures are reported for 2-4. In each structure the two triangular triosmium units are linked by the carboxylate groups and within each complex the carboxylate groups are chelating and bridge two osmium atoms.
