Growth and characterization of nonlinear optical (NLO) crystal of (((4-aminophenyl)sulphonyl) oxy)zinc(II)chloride (4-ASZC), based on zinc chloride with sulphanilic acid by the slow evaporation method has been studied and reported in this paper. The single crystal X-ray diffraction study confirmed the monoclinic system with centrometric space group P2 1 . The sharp Bragg's peak in powder X-ray diffraction analysis identifies the crystalline nature. Optical properties, such as low cut-off wavelength (251 nm), optical band gap (E g = 4.40 eV), reflectance (R), extinction coefficient (K) and refractive index (n), are calculated from the UV-vis-NIR spectrum. The presence of functional groups are confirmed by the FT-IR spectroscopy. The placement of protons and carbons was determined by the NMR technique. The photoluminescence study shows the green light emission. The grown crystal is thermally stable up to184°C. The NLO efficiency is 0.5 times greater than that of standard KDP. The mechanical properties were analysed. The dielectric constant (ε), dielectric loss (ε ), imaginary dielectric constant (ε ), AC conductivity (σ ac ) and Cole-Cole graphs were plotted. The surface morphology and the particle size of the crystal were determined by the FESEM technique. ARTICLE HISTORY

“…Thus, the upfield shift of CH proton in ammonium tartrate crystal confirms the formation of the crystal. Then the signal produced at δ = 3.97ppm corresponds to the NH4 + proton of ammonium tartrate crystal 13 . The disappearance of the signal for the acid proton in NMR of the diammonium tartrate crystal indicates that the acid proton (-COOH) of the tartaric acid involved in bond formation with the ammonium forming diammonium tartrate crystal.…”

Ammonium tartrate single crystals were grown by a solvent evaporation method. The single crystal and powder Xray diffraction studies determine the lattice parameter and showed that the crystal is monoclinic. The lower cut off wavelength was found at 220nm. The functional groups such as OH, NH4 + , COO¯, and CH declares the formation of ammonium tartrate crystal. The molecular structure was established from the NMR analysis. The thermal studies were carried out from TG/DTA experiments. The second harmonic generation efficiency was measured through Kurtz-Perry technique. The observed second harmonic generation efficiency was found to be higher than KDP and some of the reported nonlinear optical crystals.

The title compound derived from 3β-chlorocholest-5-ene has been synthesized and characterized successfully. A single crystal X-ray investigation of the compound revealed that the van der Waals interactions play a key role in the formation of the elementary structure. Hirshfeld surface analysis was used to visualize the fidelity of the crystal structure. This method permitted the identification of individual types of intermolecular contacts and their impact on crystal packing. Molecules are linked by a combination of C H• • •H and C• • •H contacts, which have clear signatures in the fingerprint plots. The absorption spectrum exhibited a strong absorption band of approximately 246 nm, and the fluorescence spectrum of the compound showed one broad peak at 367 nm. Thermal studies established that the compound undergoes no phase transition and is stable up to 200 • C. The hardness of the grown crystal increases as the load increases. The electric permittivity of cholest-5-ene decreases with increasing frequency and becomes almost constant at high frequencies.
