摘要：

The standard molar enthalpies of formation of H4SiW12O40. 6H(2)O (I), H4SiW12O40. 6DMF . H2O (II), H4SiW12O40. 8DMSO . H2O (III) have been determined. Thermodynamic cycles were designed, and the heat of reactions in the thermodynamic cycles were measured calorimetrically. The infrared spectra were compared with those of the heteropoly anion alpha-H4SiW12O40 [1] and of the ligands DMF and DMSO. The evolved gas from the adducts was monitored by a quadrupole mass spectrometer at a heating rate of 16 deg . min(-1).
