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.
