Abstract
Provided are a novel dielectric material and a novel electrostrictive material. The dielectric material or electrostrictive material comprises a charge-separation type non-coulombic ionic solid in which complex cations each composed of a metal element and a ligand are aggregated to form cation clusters, the cation clusters are arranged in a closest packed structure, and anions are aggregated to form anion clusters in interstices of the closest packed structure.

A dielectric material, comprising:
- a charge-separation type non-coulombic ionic solid in which complex cations each composed of a metal element and a ligand are aggregated to form cation clusters, the cation clusters are arranged in a closest packed structure, and anions are aggregated to form anion clusters in interstices of the closet packed structure.
An electrostrictive material comprising a charge-separation type non-coulombic ionic solid in which complex cations each composed of a metal element and a ligand are aggregated to form cation clusters, the cation clusters are arranged in a closest packed structure, and anions are aggregated to form anion clusters in interstices of the closest packed structure.
A multinuclear metal complex of formula (1a):
- (M1)l(M2)m(X1)n(X2a)o.(X3)p.qH2O (1a), wherein:
