Abstract
l-Proline lithium bromide monohydrate (LPLBM) was synthesized and its good quality bulk single crystals of size ~55×10×8mm3 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 P21. The lattice parameters of the titled compound was found to be a=8.0347(7)Å, b=5.1469(4)Å, c=10.6218Å, α=γ=90°, β=104.249(2)° and unit cell volume V=425.74(6)Å3. Elemental analysis was done by electron diffraction X-ray spectroscopy. Optical study shows that the grown crystals are highly transparent (~80%) in entire testing range. Optical band gap was calculated and found to be 5.7eV. DSC study shows that the grown crystals are thermally stable up to 273°C and two low temperature phase transitions were observed at −44.66 and 43.95°C.
