Interrelationship “structure — Nonlinear optical properties” for acentric chlorides

Structural parameters and physical properties are tabulated for >100 presently known simple and binary acentric chloride crystals. Distribution of the crystals over point symmetry groups has been defined in comparison with that of fluorides. A rosette of ellipses of acentricity has been outlined on the plane of the shortest chemical bond lengths metal-chlorine in the crystal lattice. A combination of chemical bond lengths most promising for pronounced nonlinear optical properties has been selected.
