In the title compound, C14H14NO+·C7H7O3S−, the cation is almost planar and adopts an E configuration. In the crystal structure, the cations and anions are packed as alternate layers parallel to the ac plane. These layers are interconnected through O—H⋯O, C—H⋯O and C—H⋯π interactions, forming a three‐dimensional supramolecular network.
In the title compound, C12H12NS+·C6H4ClO3S−, the cation is almost planar and exists in the E configuration. The cations and anions form alternate layers parallel to the ab plane. Within each layer, both cations and anions form chains directed along the b axis. The molecules are interconnected by weak C—H⋯O interactions into a three-dimensional network. The crystal structure is further stabilized by C—H⋯π interactions involving the thiophene ring. The sulfonate and thiophene groups are involved in weak intramolecular C—H⋯O and C—H⋯S interactions, respectively. The latter intramolecular hydrogen bonds produce S(5) ring motifs.
Five 2-aminochalcone derivatives [R = H(1), R = OCH 2 CH 3 (2), R = 2,4, (3), R = 3,4,5-OCH 3 (4), and R = thiophene(5)] were synthesized and characterized by 1 H NMR, FT-IR, and UV-Vis spectroscopy. Crystal structure of 2 was also determined by single crystal X-ray diffraction. Compound 2 crystallizes in a monoclinic P2 1 /n space group with the unit cell parameters a = 32.804 (7) Å, b = 4.9972(11) Å, c = 21.7173(3) Å, β = 128.440(4) • , V = 2788.4(10) Å 3 , and Z = 8. There are two molecules in an asymmetric unit of 2, the molecular structure of 2 is twisted with the dihedral angle between the two phenyl rings being 13.6(3) • in one molecule and 7.1(3) • in the other. In the crystal packing, the molecules of 2 are linked into chains along the b-axis by C H···O interactions. Antioxidant and antibacterial activities of 1-5 were also carried out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
