Abstract

The reaction between the acyl-substituted triosmium cluster [Os3H(CO)10(μ-COC4H4N)] and trimethylamine-N-oxide, at -78°C, yields not the expected pyrrole-linked cluster but the novel trimethylamine complex [Os3H(CO)9(NMe3)(μ-COC4H 4N)] (1). An X-ray crystal structure of the product shows that it consists of an η2-2-acylpyrrole bridged triosmium unit incorporating a terminally coordinated trimethylamine ligand which occupies an equatorial site on the osmium triangle.
