Abstract
A metal ion coordinated complex crystal is composed of cation of a nitrogen-containing heterocyclic aromatic compound, anion of triiodine and metal ion. The complex crystal can be used as light-polarizing particles having a stable and strong polarizability which is resistant to ultra violet, an excellent heat resistance, excellent moisture resistance and excellent insolubility.
