The potential organic NLO crystal of benzimidazole (BMZ) has been successfully grown by slow evaporation solution growth technique at room temperature. The crystalline perfection has been verified by High resolution X-ray diffraction (HRXRD) analysis. The very low angle boundary obtained for this solutiongrown specimen may be attributed to the segregation of solvent molecules (methanol), which were entrapped within the crystal during growth. The laser damage threshold has been measured by using high intensity Qswitched Nd:YAG laser. The observed value is greater than that of KDP and lesser than that of melt grown benzimidazole. The NLO efficiency has been determined and it is compared with the KDP crystal. The thermal behaviour has been assessed by TG/DTA analysis.

“…The shift towards low value, therefore, illustrates the transfer of carboxylic proton from carboxylic acid to Benzimidazole. The bands at 1592, 1478, 1451, and 1380 cm −1 are assigned to the aromatic C=C stretching vibrations of Benzimidazole ring which once again verifies the presence of Benzimidazole in the crystal [26]. The band observed at 1139 cm −1 is assigned to C-H inplane bending vibration of benzimidazolium ring [27].…”

A new organic charge transfer molecular complex salt of benzimidazolium salicylate (BSL) single crystals was grown by the slow evaporation solution growth technique using methanol as a solvent at room temperature. The grown crystals were characterised by single crystal X-ray diffraction (XRD) which confirms that the crystal belongs to monoclinic system with the centrosymmetric space group P2 1 / . The crystalline perfection of the grown crystal was analyzed by high resolution X-ray diffraction (HRXRD). The presence of various functional groups was identified by FTIR spectrum. UV-Vis spectral study reveals that the BSL crystal is optically transparent in the wavelength region 342 nm-1100 nm. Dielectric measurements of the crystal at various frequencies were also determined. The mechanical properties of the grown crystal were assessed using Vickers microhardness testing. Nonlinear optical property of the crystal was confirmed using Kurtz and Perry powder technique and the SHG efficiency of the BSL crystal is 0.7 times greater than that of the standard KDP crystal.

The docking study on a novel series of 7H-thiazolo[3,2-b]-1,2,4-triazin-7-one derivatives with acetylcholinesterase from Torpedo californica has demonstrated that the ligands bind to the dualsite of the enzyme. The synthesis and characterization of 7H-thiazolo[3,2-b]-1,2,4-triazin-7-one derivatives was described. The crystal structure of 6-benzyl-3-{4-[2-(1-piperidinyl)-2-oxoethoxy]phenyl}thiazolo[3,2-b]-1,2,4-triazin-7-one has been characterized by X-ray diffraction. All target compounds have been screened for their efficacy as acetylcholinesterase inhibitor. The study of AChE inhibitory activity was carried out using the Ellman colorimetric assay with huperzine-A as a reference against targets. Most of the target compounds exhibit more than 50% inhibition at 10 µM. Some derivatives showed good inhibition against AChE. The preliminary structure-activity relationships were discussed.
