L-ornithinium dipicrate (LODP) has been synthesized and good quality single crystals were grown by slow evaporation method at room temperature. Single crystal XRD confirms that the grown crystal belongs to the monoclinic system with the noncentrosymmetric space group P21. Powder X-ray diffraction study confirms the crystalline nature of the compound. FTIR spectral analysis confirms the functional group in the synthesized compound. Thermogravimetric and differential thermal analyses reveal the thermal stability of the crystal. The optical absorption spectrum shows the absence of absorption between 475 nm and 800 nm. The dielectric measurements were carried out to estimate the dielectric parameters of the grown crystal in the frequency range from 50 Hz to 5 MHz at various temperatures. The second harmonic property has been investigated by Kurtz-Perry powder technique. The relative SHG efficiency of LODP is found to be 14.57 times greater than that of the reference material KDP.
合成了L - 鸟氨酸苦味酸盐（LODP），并通过室温缓慢蒸发法生长出了高质量的单晶。单晶X射线衍射证实生长的晶体属于单斜晶系，具有非中心对称空间群P21。粉末X射线衍射研究证实了该化合物的晶体性质。傅里叶变换红外光谱分析证实了合成化合物中的官能团。热重分析和差示热分析揭示了晶体的热稳定性。光学吸收光谱显示在475纳米至800纳米之间没有吸收。进行了介电测量，以估计在不同温度下，生长晶体在50赫兹至5兆赫兹频率范围内的介电参数。通过库尔茨 - 佩里粉末技术研究了二次谐波特性。发现LODP的相对二次谐波产生效率比参考材料磷酸二氢钾（KDP）高14.57倍。
