Abstract

Vibrational spectroscopic and conductivity data are presented for complexes of NaBF₄ and NaBH₄ with poly(ethylene oxide). These studies indicate that extensive contact ion pairing occurs in the NaBH₄ complex but not in the NaBH₄ complex. As a result the ionic conductivity is considerably lower in the NaBH₄ complex, due to trapping of the mobile sodium cations by the anion. The effect of salt stoichiometry on the conductivity behavior is also reported.
