Synthesis, growth, crystal structure, EDX, UV-vis-NIR and DSC studies of L-proline lithium bromide monohydrate A new semiorganic compound

L-Proline lithium bromide monohydrate (LPLBM) was synthesized and its good quality bulk single crystals of size similar to 55 x 10 x 8 mm(3) were grown for the first time. Structural analysis was carried out by using single crystal X-ray diffraction and confirms that the crystal belongs to monoclinic system with space group P2(1). The lattice parameters of the titled compound was found to be a =8.0347(7) angstrom, b =5.1469(4) angstrom, c =10.6218 angstrom, alpha=gamma=90 degrees, 75=104249(2)degrees and unit cell volume V=425.74(6) A(3). Elemental analysis was clone by electron diffraction X-ray spectroscopy. Optical study shows that the grown crystals are highly transparent (similar to 80%) in entire testing range. Optical band gap was calculated and found to be 5.7 eV. DSC study shows that the grown crystals are thermally stable up to 273 degrees C and two low temperature phase transitions were observed at 44.66 and 43.95 degrees C. (C) 2014 Elsevier B.V.
