The crystal was grown with a growth rate of 6mm/day upto a dimension of 60 X 30 X 10 mm and within a period of 10 days having a cylindrical morphology. Single crystal XRD analysis confirms that the growth ingot belongs to the orthorhombic crystal system with a space group of P212121. The crystalline perfection was assessed by XRPD analysis. The powder diffraction pattern of the grown crystal has been indexed. The presence of C=N bond with intramolecular hydrogen bonding on the protonation of ions were confirmed by FTIR analysis. The UV-vis-NIR spectrum of the crystal shows that the crystal has cut-off wavelength at 200 nm. The 1H 1and 13 NMR spectra confirms the molecular structure. The existence of second harmonic generation (SHG) signal was observed by using ND:YAG laser with the fundamental wavelength of 1064 nm. The Laser damage threshold of PMPIB was found to be 0.57 GW/cm2 and hence PMPIB can be used in frequency doubler system. The photoconductivity study of PMPIB revealed negative photoconductivity of the sample. Copyright@ International Science Community Association
