Abstract

The total structure factors of the molten MX₃ salts HoCl₃, ErCl₃, HoBr₃ and ErBr₃ were measured by using neutron diffraction. The liquids comprise distorted MX₆ ^3- octahedral units and show intermediate-range ionic ordering as manifest by the first sharp diffraction peak at a scattering vector of ≈0.94 angstroms^-1 for the trichlorides and ≈0.80 angstroms^-1 for the tribromides. The trivalent metal halide systems show a rich diversity in behavior with ion size, adopting an increasingly `covalent' character with decreasing cation radius.
