Аl2(SO4)3 ⋅ 8(CH3)2SO ⋅ 3Н2О Glass as a Precursor for the Synthesis of Crystalline Аl2(SO4)3 ⋅ 8(CH3)2SO

The new compound Аl2(SO4)3 ⋅ 8(CH3)2SO, which cannot be prepared by direct synthesis, has been synthesized from an Аl2(SO4)3 ⋅ 8(CH3)2SO ⋅ 3Н2О glass. The compound has been identified by X-ray diffraction. Based on IR spectra, it has been concluded that the Al3+ ion has mixed coordination to dimethylsulfoxide (DMSO) molecules, and the ligands are linked to each other through the S and O atoms.
