Dielectric Jump and Negative Electrostriction in Metallosupramolecular Ionic Crystals.

ABSTRACT: In natural ionic solids, cationic and anionic species are alternately arranged to minimize electrostatic energy. Aggregation of identical ionic species is commonly prohibited due to the repulsive, long-range nature of Coulombic interactions. Recently, we synthesized unique ionic solids, [Au^I₄Co^III₂(dppe)₂(D-pen)₄]X₂·nH₂O (dppe = 1,2-bis(diphenylphosphino)ethane, D-pen = D-penicillaminate), in which complex cations are self-assembled into a cationic supramolecular octahedron, while monovalent or divalent inorganic anions are aggregated into an anomalous anionic cluster accommodating several water molecules. This quite unusual aggregation manner originates from various molecular-level non-Coulombic intera
