Density measurements are reported for 1-methyl-3-ethylimidazolium chloride + AlCl[sub 3] binary melts and for 1-methyl-3-ethylimidazolium chloride + AlCl[sub 3] + MX ternary melts, where M = Li, Na, K, Rb, or Cs and X = Cl, Br, or 1 in the temperature range 15--105 C. From these measurements molar volumes and thermal expansion coefficients were calculated. The behavior of these properties is explained by the formation of complex tetrachloro- and heptachloroaluminates in these ionic liquids and by the radii of the alkali-metal cations and halide anions. The binary and ternary melts mix ideally with respect to volume. The effective ionic radius of the 1-methyl-3-ethylimidazolium cation increases with the molar fraction of AlCl[sub 3] in the binary melt.
