Optical quality single crystals of glycine thiourea (GT), a new organic nonlinear optical (NLO) crystal, were grown from aqueous solution by slow evaporation method. Solubility of GT was determined at various temperatures. Single crystal X-ray diffraction studies indicate that GT crystallizes in the monoclinic crystal system. Various diffracting planes of the grown crystal were identified from ...
Polar organic nonlinear optical material, L-tartaric acid single crystals have been grown from slow evaporation solution growth technique. Single crystal X-ray diffraction study indicates that the grown crystal crystallized in monoclinic system with space group P21. Crystalline perfection of the crystal has been evaluated by high resolution X-ray diffraction technique and it reveals that the cr...
در یک مطالعه ی بسیار جاالب ما موفق به تهیه ی چارچوب فلز-آلی آنیونی (kmti-1) {[dimethylammonium]2[zn3(benzenedicarboxylate)4]. 8dimethylformamide} با حفراتی بزرگ شدیم. این ترکیب متشکل از لیگند آلی بنزن دی کربوکسیلیک اسید و نمک فلزی روی نیترات است که داخل حفرات آن مولکول های حلال دی متیل فرم آمید و کاتیون های دی متیل آمونیوم قرار دارند. حضور کاتیون های دی متیل آمونیوم که در اثر هیدرولیز دی متیل ف...
4-(4H-1,2,4-Triazol-4-yl)phenol (compound I) as a triazol aromatic compound was obtained by the reaction diformylhydrazineand p-aminophenol in dimethylformamide (DMF) under hydrothermal condition. The crystal structure of this compound was determined by FT-IR spectroscopy, NMR, elemental analysis and single crystal X-ray diffraction method. Crystallographic data for I was collected at 298 K. Th...
Bulk single crystals of pure and xylenol orange dye (XO) admixtured L-Alanine Thiourea (LATU) were grown by slow evaporation technique. The cell parameters and crystallinity of pure and dye admixtured LATU crystals were confirmed by single crystal, powder X-ray diffraction and high resolution X-ray diffraction analyses. The functional groups present in the crystals were confirmed by FTIR analys...
An organic nonlinear optical (NLO) single crystal has been synthesized by slow solvent evaporation technique from aqueous solutions of L-serine and sodium fluoride (NaF) at ambient temperature. The grown crystal was confirmed by single crystal X-ray diffraction analysis. The powder X-ray diffraction of the grown crystal was recorded and indexed. The functional groups of the grown crystals were ...
A single-crystal to single-crystal (SC-SC) transformation process driven by water molecules has been exhibited by a multi-metallic coordination polymer. The in situ heating single crystal X-ray diffraction technique was applied to study the control of metal ion movement in the reversible SC-SC transformation process.
The thioborate phase Ba7(BS3)4S was synthesized from solid state reaction and its crystal structure determined by single crystal X-ray diffraction analysis. It crystallizes in the monoclinic space group C2/c (No. 15) with a = 10.1750(15) A, b = 23.970(4) A, c = 10.1692(15) A, beta = 90.095(2) degrees, and Z = 4. The structure consists of isolated trigonal planar (BS3)3- anions, and isolated S2-...
Fast Li-ion-conducting Li oxide garnets receive a great deal of attention as they are suitable candidates for solid-state Li electrolytes. It was recently shown that Ga-stabilized Li7La3Zr2O12 crystallizes in the acentric cubic space group I4̅3d. This structure can be derived by a symmetry reduction of the garnet-type Ia3̅d structure, which is the most commonly found space group of Li oxide garne...
X-ray diffraction photographs of protein single crystals have been obtained using synchrotron radiation produced by an electron-positron storage ring. The diffracted intensities observed with this unconventional source are a factor of at least 60 greater than those obtained with a sealed x-ray tube using the same crystal and instrumental parameters. Diffraction data have been collected by the p...
