Crystal growth, stability and photoluminescence studies of tetra aqua diglycine magnesium (II) hexa aqua magnesium (II) bis sulfate crystal

Single crystals of tetra aqua diglycine magnesium (II) hexa aqua magnesium (II) bis sulfate have been grown from saturated aqueous solution by slow evaporation solution growth technique. The solubility of the title compound in water at various temperatures has been determined. Single-crystal X-ray diffraction analyses reveal that the title compound crystallizes in triclinic system with space group P1̄. Fourier transform infrared spectral analyses confirm the presence of functional groups in the grown crystal. The thermal stability of the grown crystal has been investigated by thermogravimetric and differential scanning calorimetric analysis. It indicates that the material is stable upto 100 °C. The crystalline perfection of the grown crystal has been evaluated by high-resolution X-ray diffraction technique. Vickers microhardness measurements indicate the mechanical strength of the grown crystal. Photoluminescence of the grown crystal has been investigated and it reveals that the crystal has blue-violet fluorescence emission.
