Abstract

Reactions between the activated cluster [Os-3(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 [Co-2(CO)(8)] and this results in the addition of a "Co-2(CO)(6)" group giving [{Os3H(CO)(10)}(2)(C2O4){Co-2(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.
