摘要：

The signals of six nonequivalent siloxy ligands(~)in the NMR spectrum confirm among other things the existence of one hydrido and one bridging 2-butenylidene ligand in complex 1. It is very likely that the hydrido ligand is terminally bonded to W2, even though there is also evidence of an exchange process between the siloxy and hydrido ligands. Complex 1, whose central framework is shown here, was also characterized by X-ray crystallography. [W2(H)(mu-CCH=CHCH3){OSi(tBu)Me2}6] 1
