Molybdenum trioxides MoO3 or MoO3. 2H(2)O reacted with alcohol ethers (HOROR') to form complexes having the general formula [MoO2(OROR')(2)] where HOROR' = 2-methoxyethanol (Hmet) or tetrahydropyran-2-methanol (Hpyr). In these compounds the Mo-VI has a distorted octahedral coordination geometry. The reaction of [MoO2(pyr)(2)] with ditertiary diol 1,1'-bicyclohexane-1,1'diol (H(2)bicy) in acetonitrile solution produced the complex [MoO2(Hbicy)(pyr)] and in the presence of methanol the product was the dimeric complex [{MoO2(Hbicy) (OMe)}(2)]. 2MeOH. The structures of four complexes were confirmed by X-ray diffraction.
