摘要：

Single crystals of semiorganic material calcium dibromide bis(glycine) tetrahydrate were grown from aqueous solution. The crystal belongs to monoclinic system, with a = 13.261(5) angstrom, b = 6.792(2) angstrom, c = 15.671(9) angstrom and beta = 91.68(4)degrees. The presence of the elements in the title compound was confirmed by energy dispersive X-ray analysis. The solubility and metastable zone width were found. The grown crystals were tested by powder XRD, FTIR, Thermo Gravimetric and Differential Thermal Analysis, UV-vis-NIR analysis, dielectrical and mechanical studies. The transmittance of calcium dibromide bis (glycine) tetrahydrate crystal has been used to calculate the refractive index n, the extinction coefficient K and both the real epsilon(r) and imaginary epsilon(i) components of the dielectric constant as functions of wavelength. The optical band gap of calcium dibromide bis(glycine) tetrahydrate is 3.23 eV. (C) 2010 Elsevier B.V. All rights reserved.
