derivatives, e.g., Os3(CO)11P(CH2CH2(CF2)5CF3)3} (1) and Os3(CO)10P(CH2CH2(CF2)5CF3)3}2 (2) have been synthesized in order to assess their properties in fluorocarbon, or fluorous, phases. Cluster 1 reacts with PPh3 above 100 °C to substitute one or two carbonyl ligands and provide the mixed ligand derivatives Os3(CO)10(PPh3)P(CH2CH2(CF2)5CF3)3}, (3) and Os3(CO)9(PPh3)2P(CH2CH2(CF2)5CF3)3}, (4).
