The formation and stability of molybdenum-antimony and tungsten-antimony ternary oxides Sb 2MO 6, Sb 2M 2O 9, Sb 2Mo 3O 12 and Sb 4MO 9 in the gas phase (M = Mo, W). Quantum chemical and mass spectrometric studies

摘要

The ternary oxides Sb 2MO 6, Sb 2M 2O 9, Sb 4MO 9 (M = Mo, W) and Sb 2Mo 3O 12 were detected in the gas phase by means of mass spectrometry (MS). These gaseous oxides are reported for the first time. Thermodynamic data was obtained experimentally and confirmed by quantum chemical (QC) calculations. In addition, structural data on these molecules was obtained. The ionisation potentials (IP) were also determined both experimentally and theoretically. © 2012 The Royal Society of Chemistry.
