  Oxygen transfer from peroxometalates as a new and general route to the synthesis of oxopolymetalates: rational synthesis of Mo2O72-, MO6O192- and MO7O246-. Evidence of a M2O72- with linear M-O-M axis

  摘要：

  The oxopolymolybdates, [Mo2O7]2-, [Mo6O19]2- and [Mo7O24]6- have been obtained via oxygen transfer reaction from a peroxomolybdate [Mo2O2(mu-2-O)(O2)4(H2O)2]2-, obtained by the treatment of HOOH on MoO3. In the case of dimolybdate, the oxygen acceptor is Ph3P, while Ph3GeCl functions as an oxygen receptor for the generation of higher polymolybdates. Three dimensional X-ray structure analysis indicates that (PPN)2[Mo2O7] contains a linear Mo-O-Mo axis and MoO3 oxygens in each fragment are staggered with respect to those of the other. The structural identity of the PPh4 and PPN salts of hexamolybdate and the PPh4 salt of heptamolybdate has been established by their superimposable X-ray powder diffractogram with those of the respective authentic samples prepared. This work presents further evidences in favour of our recent contention that peroxometalates serve as a useful precursor intermediate for the synthesis of oxopolymetalates.

  Various trialkylchlorosilanes were reacted with a number of molybdenum-oxo complexes in order to establish the main factors which influence the process of addition of the Si-Cl function across the Mo=O bond. A novel intermolecular mode of hexaalkyldisiloxane formation was observed in one case.

  The synthesis and characterisation of (PPh4)(2)[M(CN)(4)O(pz)]. 3H(2)O (M = Mo or W; pz = pyrazine) are presented. The salts are reactive towards molecular oxygen, both in solution and in the solid state, with formation of (PPh4)(2)[M(CN)(4)O(O-2)]. The X-ray crystal structure of the molybdenum compound confirmed the presence of a peroxo ligand cis to the M=O bond; the O-O bond distance is 1.41 Angstrom. The IR spectra exhibit two absorption bands in the 950-850 cm(-1) region assigned to the terminal M=O group [917 (Mo) and 933 (W) cm(-1)] and the peroxo group [893 (Mo) and 871 (W) cm(-1)]. The possible mechanism of molecular oxygen uptake by pyrazine complexes is discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
