An organic single crystals of Tertiary butylammonium maleate monohydrate (TBAMM), were grown by slow evaporation technique. The structure of the grown crystal was elucidated using single crystal X-ray diffraction analysis. XRD studies reveal that TBAMM crystal belongs to the monoclinic crystal system with space group P21/n. The presence of functional groups in TBAMM crystal was identified by FTIR spectral study. The molecular structure of the grown crystal was analyzed by NMR spectral analysis. Thermal behavior and stability of TBAMM were studied by TG/DTA analyses. UV-Vis-NIR spectral study shows wide transmission range with lower cut-off wavelength as 341nm. The optical band gap was found to be 3.13 eV from the Tauc's plot. The Second Harmonic Generation (SHG) efficiency of the TBAMM crystal was found to be 1.5 times more than that of KDP crystal. © 2015, Sphinx Knowledge House. All rights Reserved.

A noncentrosymmetric, organic single crystal, 2-amino 4-methylpyridinium tartrate monohydrate was synthesized and grown by slow evaporation solution technique at room temperature using methanol as a solvent. The cell parameters of the grown crystal were determined by single crystal X-ray diffraction method. The various functional groups present in the crystal and the different types of protons and carbons were identified by the FTIR and NMR spectral analyses. Optical properties were determined by UV-vis-NIR spectroscopic and photoluminescence studies. The second harmonic generation of the grown crystal was observed by Kurtz Perry powder technique. Photoconductivity studies were carried out for various voltages applied on the grown crystal. The thermal and mechanical stabilities of the 2-amino 4-methylpyridinium tartrate monohydrate single crystal were investigated by TGA-DTA and Vickers microhardness measurements, respectively. © 2015 Elsevier GmbH.
