Ion-solvent interactions: Conductance behavior of NaAlBu4 and Bu4NAlBu4 in benzene and tetrahydrofuran

Conductance measurements are reported for NaAlBu ₄ and Bu ₄ NAlBu ₄ in benzene and in tetrahydrofuran (THF) from a concentration of approximately 5×10^?3 M to the fused state for each salt. This is the first reported study where a comparison of a salt with a small cation is made with one having a large cation in a noncomplexing solvent (benzene) and a complexing solvent (THF). The similarity in conductance behavior in THF and the differences in benzene are considered in terms of ion-ion and ion-solvent interactions.
