A synthesis and crystal structures of three inclusion compounds of Bis(4-hydroxyphenyl) Sulfone and tetraalkylammonium

Abstract

In this paper, three inclusion compounds formed by Bis(4-hydroxyphenyl) Sulfone and tetramethylammonium cation, tetrapropylammonium cation and tetrabutylammonium cation were prepared: 4(CH₃)₄N⁺·2C₁₂H₉O₄S^-·C₁₂H₈O₄S^2-·3C₁₂H₁₀O₄S·7H₂O (1), (n-C₃H₇)₄N⁺·C₁₂H₉O₄S^-·0.5H₂O (2), 2(n-C₄H₉)₄N⁺ ·2 C₁₂H₉O₄S^- ·C₁₂H₁₀O₄S (3), then the complexes were characterized by X-ray single crystal diffraction. The results show that 1 and three belong to the monoclinic P21/c space group, while two belongs to the monoclinic Cc space group. Among the three clathrate crystal structures, one shows the anion hydrogen bond network structure with "Hourglass"-shaped pores constructed by the host molecule and its anion and water molecule; two rectangular holes are constructed from the host anion and water molecules, and these holes are repeatedly arranged to obtain a 3 D host hydrogen bond network structure; the host molecules and their anions in 3 form discrete "molecular pillars" and further pile up to form the main frame structure. As for the tetraalkylammonium cation as the guest template, they are respectively filled in the above-mentioned host frame structure to form the final stable clathrate crystal structure.
