No full textReaction of the crystallographically characterised [Y(C5Me5)(OC6H3Bu(t)2)2] 2 with LiCH(SiMe3)2 affords the mixed alkyl-alkoxide species [Y(C5Me5){CH(SiMe3)2}(OC6H3Bu(t)2)] 3 which, on subsequent hydrogenation, gives the hydride bridged dimer [{Y(C5Me5)(OC6H3Bu(t)2)(mu-H)}2] 4; Y-89 NMR spectra of these, and related complexes, allows C5Me5, OC6H3Bu(t)2 and CH(SiMe3)2 group contributions to be determined
