Vibrational spectra and structure of the heptahydrodiborate ion, [B2H7]- in glycol ethers

Abstract

The i.r. and Raman spectra of the heptahydroborate ion, [B2H7]-, and its deuterated derivative, [B2D7]-, have been obtained in solution and assignments have been made of the observed bands. The data are interpreted as indicating a bent C2 structure in solution. Normal coordinate calculations based on this model are presented.
