Electrical conductances, viscosity, apparent molar adiabatic compressibilit
ies and Fourier transform (FT)Raman spectra of sodium perchlorate (NaClO4),
sodium tetrafluoroborate (NaBF4), and sodium tetraphenylborate (NaBPh4) in
1,2-dimethoxyethane have been-reported. All these electrolytes are found t
o be strongly associated in this solvent medium. Both ion pairs and triple
ions are found to be formed though an overwhelming fraction of each of thes
e electrolytes exists as ion pairs. For NaClO4, the solvent-separated ion p
airs predominate over the contact species. For NaBF4 and NaBPh4, on the oth
er hand, the contact species are also formed in significant amounts. FT-Ram
an studies indicate the presence of "spectroscopically free" ClO4-, BF4-, a
nd BPh4- ions in 1,2-dimethoxyethane solution. The ClO4- ion is found to be
significantly solvated,; whereas BF4- and BPh4- ions are poorly solvated i
n DME solution.
