Abstract: Reaction of pentaethylcyclophosphine, (EtP)5, with triosmium cluster [Os3(CO)10(NCMe)2] in dichloromethane at room temperature afforded [Os3(CO)10{1,2-(EtP)5)] (1) with an unusual 1,2-chelation mode for the cyclophosphine. The same reactants at a higher temperature gave rise to [Os3(CO)10{1,3-(EtP)5}] (2). Treatment of the same ligand with triosmium cluster [Os3(CO)11(NCMe)] yielded several new clusters [Os3(CO)11(EtP)5}] (3), [{Os3(CO)11}2{1,3-(EtP)5}] (4), [{Os3(CO)11}2{1,2-(EtP)5)] (5), [Os3(CO)10{1,2,3-(EtP)5)Os3(CO) 11] (6) and [Os3(CO)10{1,2,4-(EtP)5)Os3(CO) 11](7).
