The Ornstein-Zernike equations for the structure of a fluid of positive ions in equilibrium with a disordered matrix formed by chlorine ions are solved numerically in the hypernetted-chain approximation, and the results are compared with those obtained for the corresponding molten 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 order of the metal-ion component is accompanied by an enhancement of its state of intermediate-range order in models appropriate to trivalent metal halides with octahedral- or tetrahedral-type coordination.
