TMNO-activated ligand substitution in the fused ring compounds Os3(μ-SbPh2)2(CO)10, 1, and Os3(μ-SbPh2)3(Cl)(CO)9, 2, in acetonitrile affords the mono- and disubstituted CH3CN-derivatives. The initial product of CH3CN substitution in 1 is an equatorial isomer, which can isomerize to the axial isomer upon heating; they are the first examples in which both isomers have been characterized crystallographically. Subsequent
