The reaction of 2-aminophenyldiphenylphosphine (2-PNH2) with and has yielded the compounds and respectively.The compounds have been characterized spectroscopically and the structure of one of them determined by an X-ray diffraction study.The ligand bridges an edge of the triosmium triangle with the P atom bound to a single Os atom in an equatiorial site.The amido N forms a bridge between this Os atom and one of its neighbours in the triangle.Key words: Triosmium; Cluster; Phosphine

Several complexes of the type M3Ln have been prepared and their reactions studied.Predominant were H-migrations from the aryl substituent X to cluster; less facile were C-C bond cleavage reactions, and P-C bond cleavages were not observed.Under the conditions used, the complexes Ru3(CO)11 were transient intermediates in the formation of Ru3(μ-H)(CO)9; the analogous Ru3(μ-dppm) and Os3(μ-dppm) complexes were more robust.Similar reactions were found for clusters made by reaction of Ru3(CO)12 and related complexes with PPh2, in which H-migration from the ligand to the cluster results in formation of a phosphino-enolate system.X-ray structures are reported for the complexes Os3(CO)11 , Ru3(μ-dppm)(CO)9 , Ru3(μ-H)(CO)9 , Ru3(μ-H)>(μ-dppm)(CO)7, Ru3(μ-H)(μ-dppm)(CO)7 and Os3(μ-H)(CO)9. Key words: Ruthenium; Osmium; Carbonyl; Functional phosphines
