Abstract
The complexes [Os3(CO)11(EMe2Ph)] or [Os3(CO)10(EMe2Ph)2](E = P or As) on heating give C6H4-bridged complexes [HOs3(C6H4)(EMe2)(CO)9], [HOs3(C6H4)(PMe2)(PMe2Ph)(CO)8]. [Os3(C6H4)(Eme2)2(CO)7], and [HOs3(Me2PC6H4C6H3)(PMe2)(CO)8]. When E = As, dimeric complexes containing bridging C6H4 are also obtained. Structures and mechanisms of the fluxional behaviour of these complexes are discussed in the light of n.m.r. spectra.Keywords
