Growth and characterization of a new nonlinear optical crystal: Bis Thiourea Zinc Chloride

Bis Thiourea Zinc Chloride (BTZC) a new semiorganic nonlinear optical mater ial has been synthesized. The solubility studies have been carried out in t he temperature range 30 degrees- 55 degreesC. Single crystals of BTZC have been grown by slow evaporation of saturated aqueous solution at room temper ature. The lattice parameters of the grown crystals have been determined by single crystal Xray diffraction technique. The UV-Vis-NIR transmittance sp ectrum has been recorded in the range 200 - 2000 nm. The FT-IR spectrum has been recorded in the range 400 - 4000 cm(-1) and the spectral bands have b een compared with similar thiourea complexes.
