Physico-chemical study of new supramolecular-architectured hybrid organic-inorganic sulfates incorporating diammoniumdiphenylsulfone cations.

ABSTRACT: Two new hybrid organic-inorganic compounds, which incorporate 3,3'-diammoniumdiphenylsulfone or 4,4'-diammoniumdiphenylsulfone cations and sulfate anions, were synthesized and analyzed in detail. The crystal structures of both systems were established using single-crystal X-ray diffraction analysis. Crystallographic study revealed that the crystals of both investigated compounds were constructed of repeatedly occurring organic and inorganic layers and allowed the description of their structural features. Dense networks of N-H⋯O hydrogen bonds were found in both crystals. In addition, S-O⋯π contacts and weak C-H⋯O hydrogen bonds were identified in each analyzed crystal network. All intermolecular interactions were quantitatively described by Hirshfeld surface analysis. Furthermore, a ¹³C NMR study was conducted for the grown crystals. The functional groups present in the titular compounds were also the subjects of IR and Raman spectral studies. Finally, TGA/DSC and UV-vis absorption measurements were performed and allowed the thermal and optical characterization of the titular materials.
