Slow evaporation method was employed to grow an organic crystal: guanidinium hydrogen succinate (GHS). Monoclinic structure of GHS was confirmed by single-crystal X-ray diffraction study and its space group was determined to be $${P2}_{1}/{c}$$P21/c. Different functional groups present in GHS were estimated qualitatively by Fourier transform infrared analysis. The crystalline quality of the grown GHS was ascertained by high-resolution X-ray diffraction study. The UV–Vis absorption spectrum reveals a lower cut-off wavelength of 235 nm. The minimum absorption shows the wide optical transparency in the entire visible region. Work hardening co-efficient value ($$n = 1.7$$n=1.7) shows that the GHS crystal belongs to soft material category. Behaviour of dipoles in the crystal was examined through dielectric study. The third-order nonlinear optical analysis was carried out on GHS crystal through Z-scan technique. The nonlinear refractive index $$(n_2)$$(n2), nonlinear absorption coefficient ($$\beta $$β) and third-order nonlinear optical susceptibility ($$\chi ^{(3)}$$χ(3)) were estimated to be $$ - 5.78 \times 10^{-8}\hbox { cm}^{2}\hbox { W}^{-1}$$-5.78×10-8cm2W-1, $$0.72 \times 10^{-4}\hbox { cm W}^{-1}$$0.72×10-4cmW-1 and $$8.09 \times 10^{-6}\hbox { esu}$$8.09×10-6esu, respectively.Graphical Abstract:

琥珀酸氢胍单晶的生长、光谱、机械、电学和光学表征

采用缓慢蒸发方法生长有机晶体：琥珀酸氢胍（GHS）。GHS的单斜结构经单晶X射线衍射研究证实，其空间群为$${P2}_{1}/{c}$$P21/c。GHS 中存在的不同官能团通过傅里叶变换红外分析进行定性估计。通过高分辨率 X 射线衍射研究确定生长的 GHS 的结晶质量。UV-Vis 吸收光谱显示较低的截止波长为 235 nm。最小吸收表明在整个可见光区具有宽的光学透明度。加工硬化系数值（$$n = 1.7$$n=1.7）表明 GHS 晶体属于软材料类别。通过介电研究检查晶体中偶极子的行为。通过Z-scan技术对GHS晶体进行三阶非线性光学分析。非线性折射率$$(n_2)$$(n2)、非线性吸收系数($$\beta $$β)和三阶非线性光学磁化率($$\chi ^{(3)}$$χ(3 )) 估计为 $$ - 5.78 \times 10^{-8}\hbox { cm}^{2}\hbox { W}^{-1}$$-5.78×10-8cm2W-1, $0.72 \times 10^{-4}\hbox { cm W}^{-1}$$0.72×10-4cmW-1 和 $$8.09 \times 10^{-6}\hbox { esu}$8.09×10-6esu，分别。图形摘要：
