STRUCTURE OF IONIC FLUIDS IN EQUILIBRIUM WITH A MICROPOROUS IONIC MATRIX

The Ornstein-Zernike equations for the structure of a fluid of positiv e ions in equilibrium with a disordered matrix formed by chlorine ions are solved numerically in the hypernetted-chain approximation, and th e results are compared with those obtained for the corresponding molte n salt at complete equilibrium. Quenching of the halogen framework in a model appropriate to CuCl enhances the delocalization of the Cu ions . A similar, although less striking, reduction in the short-range orde r of the metal-ion component is accompanied by an enhancement of its s tate of intermediate-range order in models appropriate to trivalent me tal halides with octahedral- or tetrahedral-type coordination.
