Conversion of a nitrile ligand into an amido group on a cluster surface; X-ray characterisation of [HOs4(CO)12{µ3-N(CO)Me}MPPh3](M = Au or Cu)
Abstract
The reaction of [H3Os4(CO)12(NCMe)2]+ with [N(PPh3)2]NO2 yields [HOs4(CO)12{µ3-N(CO)Me}]– by a novel conversion of an acetonitrile ligand into an amido group on the cluster surface; the anion reacts with [MPPh3]+(M = Au or Cu) to produce the neutral derivatives [HOs4(CO)12{µ3-N(CO)Me}(MPPh3)] which have been characterised by X-ray diffraction.
