30) Roux, B.; Yu, H. A.; Karplus, M.Room-temperature molten salts consisting of 1-methyl-3-ethylimidazolium chloride ((MEI)Cl), AlCl,, and NaCl (buffer) have been investigated using "C NMR relaxation methods. Results of 27Al NMR, IR, apd theoretical studies of (ME1)Cl-AICl, melts initially supported a stack model in which anions were located between stacked 'parallel" MEI+ ring planes. This was followed by a hydrogen-bonding model where anions bonded with the hydrogens on the C2, C4, and C5 members of the MEI' ring. The present "C NMR and viscosity study indicates that AIC1, in the melt forms a complex by interacting with the C2, C4, and C5 hydrogens on the MEI' ring. B. J.; Stech, D. J.; Vaughn, R.
