Abstract

Triosmium cluster Os3(μ-H)(CO)10(μ-σ-η2-C≡CC Me2OMe) (1) was obtained by treating OS3(μ-H)(μ-Cl)(CO)10 with LiC≡CCMe2OMe. The reaction of cluster1 with HBF4 · Et2O at −60 °C leads to the cationic complex [Os3(μ-H)(CO)10(μ-σ,σ,η2-C=C=C Me2)]+BF4 − (2) with an allenylidene ligand. Thes1H and13C NMR spectra of complex2 reveal the temperature dependence caused by migration of hydrocarbon and carbonyl ligands. Thermodynamic parameters were obtained for be exchange process of the allenylidene ligand.
