✦ Synopsis

Single crystals of semiorganic material triglycine calcium dibromide (TGCB) were grown from aqueous solution. The solubility and metastable zone width were found.

Single crystal X-ray diffraction analysis was used to estimate the cell parameters of the grown crystals. The structural perfection of crystals has been analyzed by high-resolution X-ray diffraction (HRXRD) rocking curve measurements. Energy dispersive X-ray analysis confirms the presence of elements in the title compound. The grown crystals were tested by FTIR, thermogravimetric and differential thermal analysis, UV-vis-NIR analysis, and dielectrical and mechanical studies. The transmittance of TGCB crystal has been used to calculate the refractive index n, the extinction coefficient K and both the real e r and imaginary e i components of the dielectric constant as functions of wavelength. The second harmonic conversion efficiency of TGCB was determined using the Kurtz and Perry powder technique; it was observed to be greater than that of KDP.
