SYNTHESIS OF A TRIOSMIUM CARBONYL CLUSTER COMPLEX WITH A SIDE-ON-COORDINATED IMINE LIGAND

A triosmium cluster with a novel side-on coordinated imine ligand has been synthesized by the reaction between a triosmium carbene complex and ammonia. In the first step of the reaction, an anionic amino complex is formed which reacts upon treatment with [Ph3C]+ to abstract a hydride from the amino group to form the imine complex, the molecular structure of which has been determined.
