Abstract:
The stability of gaseous BMoO(4) was confirmed by Knudsen effusion mass spectrometry. The gas-phase reaction involving B(2)O(3), MoO(2), MoO(3) and BMoO(4) was studied. On the basis of the equilibrium constants, the standard formation and atomization enthalpies of gaseous BMoO(4) (-744.1 ± 24 kJ mol(-1) and 2963 ± 25 kJ mol(-1), respectively) at 298 K were determined. To obtain the structure parameters and vibrational frequencies of gaseous BMoO(4), a quantum chemical investigation of this molecule was undertaken. Based on the critical analysis of the literature data concerning the standard formation enthalpies of gaseous BWO(4), BPO(4) and BPO(3), we adopted new values for Δ(f)H(0)(298) which are equal (-934.4 ± 29.3 kJ mol(-1), -975.8 ± 16.2 kJ mol(-1) and -717.0 ± 19.3 kJ mol(-1)), respectively.
