A preliminary X-ray study of the title molecular salt, [Ni(CH4N2S)6](NO3)2, has been reported twice previously, by Maďar [Acta Cryst. (1961), 14, 894] and Rodriguez, Cubero, Vega, Morente & Vazquez [Acta Cryst. (1961), 14, 1101], using film methods. We confirm the previous studies, but to modern standards of precision and with all H atoms located. The central Ni atom (site symmetry ) of the dication is octahedrally coordinated by six S-bound thiourea molecules. The crystal structure is stabilized by intra- and intermolecular N—H⋯S and N—H⋯O hydrogen bonds.

A single crystal of gamma-glycine (GG), a polymorph of glycine, was synthesized by crystallization. The single crystal of GG was grown from an aqueous solution. The morphology of GG was studied in order to assess its growth facets. The good quality single crystals were subjected to X-ray diffraction studies to reveal their structure. The FT-IR spectral analysis was carried out to confirm the presence of expected functional groups. The UV-Vis analysis was done for GG single crystals to determine the optical transparency and band gap. Simultaneous TG-DTA analysis was employed to understand the thermal and physicochemical stability of the title compound. The mechanical stability and laser stability of GG single crystal were studied using Vickers microhardness test and laser induced damage threshold on different planes of the crystal to reveal its anisotropic nature. The dielectric measurement was carried out as a function of frequency and the results were discussed. The existence of second harmonic generation (SHG) of the title compound was confirmed by Kurtz-Perry powder technique. The SHG effective nonlinearity and particle size dependence of GG powder sample were compared with a standard reference material: potassium dihydrogen phosphate (KDP).

“…Bis-thiourea cadmium chloride exhibits the highest laser-induced damage threshold values compared with other similar crystals. 10 Recently, a few more urea-based semi-organic NLO crystals are reported, for instance, tertrakis thiourea nickel chloride, 11 bis-thiourea bismuth chloride, 12 and zinc tris-thiourea sulphate. 13 As other thiourea compounds are expected to show NLO properties the present authors have attempted to synthesize bis-thiourea strontium chloride (BTSC) and grow single crystals by the slow solvent evaporation method, which is for the first time reported in the present communication as per the current knowledge of the authors.…”

Bis-thiourea strontium chloride was synthesized and single crystals were grown by the slow solvent evaporation technique using aqueous solvent. The solubility curve was obtained and the determination of the induction period as well as the evaluation of kinetic parameters of nucleation was carried out. The powder XRD analysis suggested orthorhombic crystal structure. The FT-IR spectrum confirmed the presence of various functional groups. The thermo-gravimetry analysis was carried out and the crystals were found to be stable up to 170 • C. Applying Coats and Redferm relation to the thermogram, the kinetic and thermodynamic parameters of dehydration were calculated. The dielectric study was carried out in the frequency range of applied field from 500 Hz to 1 MHz. The variations of dielectric constant, dielectric loss, AC resistivity and AC conductivity were studied with frequency. It was found that the dielectric constant and the dielectric loss decreased as the frequency of applied field increased, whereas the AC resistivity increased as the frequency increased.
