Niobium selenides

The only well-established, structurally characterized mixed valence compounds are the niobium selenide derivatives Nb3Se5Ciy/IV and [(MeCN)2Br2Nb( U-Se)2( U-Se)NbBr2-(MeCN)2]IV/m (Section 34.3.4). [Pg.685]

The reactions of 1,2,5-triphenylphosphole (tpp)(46), 1,2,5-triphenylphosphole oxide (tppO), sulphide (tppS), and selenide (tppSe), with niobium(v) and tan-talum(v) halides in dry, oxygen-free organic solvents have been studied. The complexes formed were characterized by i.r. and X-ray spectroscopy. The... [Pg.73]
