A fresh analysis has been performed on the original electron-diffraction data for saturated thallium monofluoride vapor.The diffraction data have been combined with spectroscopic ones to derive the equilibrium geometry and the complete harmonic force fiel

A colorimetry study of thallium pentafluorotellurate (IV) indicates a reversible phase transition near 192 K. Powder diffraction analysis has been performed for the high and low-temperature forms. Structural data are: form I (298 K): monoclinic system; a equals 14. 099 angstrom, b equals 6. 510 angstrom c equals 11. 864 angstrom, beta equals 91. 03 degree ; form II (123 K): monoclinic system; a equals 14. 218 angstrom, b equals 8. 825 angstrom, c equals 8. 559 angstrom, beta equals 91. 2 degree . These results are discussed in comparison with the thermodynamic characteristics of the I yields II transition.
Matrix-isolation study of oxide-transfer reactions to halogen-containing Lewis acids: Synthesis of the CO2F22- anion and attempted synthesis of the BF3O2- anion

The oxide-transfer technique has been coupled with matrix isolation in an attempt to synthesize and characterize the BF3O2- and CO2F22- anions, through the reaction of Tl2O with either BF3 or COF2. In the latter experiments, two sets of product bands were observed; one agreed well with the absorptions of the known CO2F- anion. The second set has been assigned to the CO2F22- anion in the matrix-isolated Tl+2CO2F22- triple ion, which rapidly eliminated TlF upon warming to form the Tl+CO2F- anion. Attempts to synthesize the BF3O2- anion in a similar fashion were not successful, suggesting that previous reports of the room-temperature synthesis of this anion are incorrect.
