Abstract
With [(C9H7)Rh(PiPr3)] as molecular unit and diphenylketene as ligand, it has been possible for the first time to isolate linkage-isomeric ketene metal complexes (1 and 2). With regard to the hard/soft acid/base (HSAB) concept, it is surprising that the η2(C,O)-bonded isomer is thermodynamically more stable than the η2(C,C)-bonded counterpart.
