Vibrational spectra of trihaloselenate(IV) ions, SeOX3-

Several trifluoro- and tribromoselenate(IV) compounds, MSeOF3 and MSeOBr3, have been made and characterized by IR and Raman spectroscopy. Comparison of the spectra with those of the trichloroselenate(IV) compounds previously reported has been made. In all cases the spectra are consistent with trigonal-bipyramidal stereochemistry predicted by valence-shell-electron-pair repulsions with the oxygen and lone electron pair equatorial. Anion polymerization via oxygen or halogen bridging is very weak for MSeOF3 (M = K, Cs) but becomes significant for MSeOCl3 where M = K and for MSeOBr3 where M = Me4N. Compounds with larger cations contain isolated SeOX3- anions. Normal-coordinate analysis has been used to assist in assigning the spectra. The force constants calculated show the equatorial halogen is more strongly bound to selenium than is the axial halogen.
