identified by elemental analysis and IR spectral data. The X-ray diffraction analysis of (H2Bipy)[Sc(H2O)(SO4)2]2 · 2H2O shows that in the structure of this compound, the chains of ScO6 octahedra and SO4 tetrahedra are united to form ribbons due to the tridentate coordination of the sulfate ion. The ribbons form a framework, whose infinite cavities contain H2Bipy2+ cations.

feasible production of scandium oxide – has been prepared using a hydrothermal route. The sample was characterized by X-ray powder diffraction (XRPD), IR spectroscopy, scanning electron microscopy, and thermal and elemental analysis. The high-temperature XRPD and thermal studies revealed an enantiotropic first-order phase transition at 81.6 °C and standard pressure. In the temperature region of 80–100
