Abstract

The co-ordination behaviour of molybdenum(VI) towards diols and aminoalcohols is discussed, particularly in relation to newly determined reference structures. A pinacol (H2pin) complex, typical of the yellow vicinal diol derivatives, is constituted [MoO(pin)(Hpin)]2O, with an Mo2O3 core. An Mo2O5 core is present in the anion [{MoO2(Hnta)}2O]2–, formed by nitrilotriacetic acid (H3nta) at low pH. Several new complexes in which ligand bridging is inferred have been prepared. One of these, [{MoO2(Hpin)(OMe)}2]·2MeOH, which is derived from the yellow pinacolate, is shown by X-ray analysis to have methoxy-bridging. The bridge vibration from an Mo2O3 core is close to 750 cm–1, but the pattern of bands from an Mo2O5 core is variable. The MoO1bMo vibration involving an oxygen bridge provided by a chelating ligand gives an i.r. band in the region 625–650 cm–1.
