Guanidinium Para-Substituted Benzenesulfonates: Competitive Hydrogen Bonding in Layered Structures and the Design of Nonlinear Optical Materials

Crystal structure of tetrabutylammonium 4-aminobenzenesulfonate 2/3 hydrate, C22H42N2O3S · 2/3 H2O

“…At the same time, the amino group is a hydrogen bond acceptor. Searching in CSD database [1], it can be found that sulfanilic acid can interact with various compounds, such as varied organic cations [2][3][4][5][6] and metal ions [7,8], to form complicated crystal structures. However, the title structure has not been reported before.…”

Crystal structure of tetraethylammonium 4-aminobenzenesulfonate, C14H26N2O3S

“…At the same time, the amino group can be thought of as a good hydrogen bond acceptor. Searching in CSD database [1], it can be found that sulfanilic acid can interact with various compounds, such as varied organic cations [2][3][4][5][6] and metal ions [7,8], to form complicated crystal structures. As part of a systematic study of the related crystal structures, the title compound was synthesized and its crystal structure is reported here.…”

Crystal structure of tetramethylammonium sulfanilate, C10H18N2O3S

“…It also can be found the acid can lose its proton of the sulfonate to become the related anion to interact with di erent organic cations such as ammonium [2], methylammonium [3], hydroxylammonium [4], guanidinium [5] and triethylammonium [6]. However, the crystal structures of the acid and the tetraalkylammonium cations have not been reported before.…”
