C. Aubauer et al., An experimental and theoretical study on the novel tetraphosphorus triselenide boron triiodide (P4Se3)center dot(BI3) adduct, J MOL MODEL, 6(2), 2000, pp. 76-85
Tetraphosphorus triselenide boron triiodide (P4Se3).(BI3) has been prepared
. The product formed has been characterized by Raman and IR spectroscopy. V
ibrational assignments for the normal modes of this Lewis acid-base adduct
have been made on the basis of comparison between theoretically obtained an
d experimentally observed Raman and IR data. The geometries of several poss
ible tetraphosphorus triselenide boron triiodide (P4Se3).(BI3) adducts have
been calculated. The bonding and electron transfer from the tetraphosphoru
s triselenide P4Se3 unit to the Lewis acid BI3 has been investigated by app
lying NBO analysis.
