Abstract

Dimolybdenum tetratrimethylacetate (tetrapivalate) and tetratrifluoroacetate are synthesized, and their evaporation is studied by the Knudsen effusion method with mass spectral analysis of the gas phase. The standard enthalpies of formation of crystalline and gaseous Мо2(СF3COO)4 are estimated for the first time by the study of dissociative ionization. The solid-phase reactions of silver pivalate (CН3)3СCOOAg with molybdenum are studied by thermography (TG), differential scanning calorimetry (DSC), and mass spectrometry. The reaction in a temperature range of 410–480 K affords molybdenum oxopivalate МоО2Piv2. The obtained experimental data make it possible to estimate the standard enthalpy of formation of this compound: ΔfH°298 (МоО2Рiv2, cr) = –1476 kJ/mol.
