• Molybdenum(VI) equilibria in different ionic media. Formation constants and thermodynamic quantities

  Molybdenum(VI) equilibria have been investigated in LiClO4, (2.0 M) and NaCl (1.0 and 2.0 M) media by potentiometry, molybdenum-95 NMR and calorimetry. In the case of 2.0 M Li(ClO4) and 2.0 M Na(ClO4) media the molybdenum concentration was 1.0 M and the pH range covered was 2-7.5. For the potentiometric measurements in 1.0 M NaCl the molybdenum concentration was varied from 0.1-5.0 x 10(-4) M and the pH range covered 1.0-6.5. Reaction models, based on computer treatment of the potentiometric data. have been established which are consistent with NMR information. These reaction models differ from most of those previously published in that the protonated heptamolydates [H2Mo7O24](4) and [H3Mo7O24](3) are not included. In 1.0 M NaCl at 25 degreesC the formation constants of the polyoxoanions, denoted by beta(pq), where the subscripts p and q refer to the stoichiometric coefficients of [MoO4](2-) and H- in the reactions. have the values: log beta(78) = 52.86. log beta(79) = 57.25, log beta(68) = 49.53, log beta(8.11) = 67.90. log beta(8.12) = 71.52, log beta(13.21) = 119.49 and log beta(18.32) = 171.43. Enthalpy and entropy changes for the formation of the polyions were calculated from the calorimetric data using these constants. The enthalpy values are DeltaH(78) = -258, DeltaH(79) = -248, DeltaH(68) = -218, DeltaH(8.11) = -275. DeltaH(8.12) = -285, DeltaH(13.21) = -508 and DeltaH(18.32) = -782 kJ mol(-1).

• Nuclear and electronic contributions to the photoreactivity of iso- and hetero-polyoxomolybdates
  作者：Bela Kraut、Guillermo Ferraudi

  DOI：10.1039/dt9910002063

  日期：——

  Ligand-radical intermediates were detected in flash photolysis of the hexa- and octa-molybdates. The transients exhibited absorption spectra with maxima near 460 nm and lifetimes shorter than 1 ns. The photochemical transformations of these complexes are similar to those of the heptamolybdate and heteropolyoxomolybdates. The effect of the molecular structure on the electronic levels of iso- and hetero-polyoxomolybdates was investigated with an extended-Huckel method in order to rationalize their photochemical behaviour.
