HPLC studies of Os3(CO)12-n(CH3CN)n (n = 0, 1, 2)

Abstract

Normal and reverse phase chromatographic separation of Os3(CO)12, Os3(CO)11- (CH3CN) and Os3(CO)10(CH3CN)2 have been examined. On a silica column good separation of these clusters can be achieved with CH2Cl2/petroleum ether as the mobile phase but better reproducibility is attained with a Hypersil ODS C18 column and a mobile phase of MeOH/CH3CN. The relative retention times correlate qualitatively with molecular structures. The identities and purities of the chromatographic peaks were determined by use of a Data Evaluation Pack. © 1989.
