The title compounds, C(20)H(25)N(2)O(2)S(+).I(-), (I), and C(29)H(25)BrN(2)O(2)S, (II), respectively, both crystallize in space group P-1. The pyrrole ring subtends an angle with the sulfonyl group of 33.6 degrees in (I) and 21.5 degrees in (II). The phenyl ring of the sulfonyl substituent makes a dihedral angle with the best plane of the indole moiety of 81.6 degrees in (I) and 67.2 degrees in (II). The lengthening or shortening of the C-N bond distances in both compounds is due to the electron-withdrawing character of the phenylsulfonyl group. The S atoms are in distorted tetrahedral configurations. The molecular structures are stabilized by C-H.O and C-H.I interactions in (I), and by C-H.O and C-H.N interactions in (II).
In the title compound, the acenapthylene ring system and the hydrazinecarbothioamide unit (=N—NH—C=S—NH–) are essentially coplanar, making a dihedral angle of 1.59 (9)°. The molecular conformation is stabilized by two weak intramolecular hydrogen bonds (N—H⋯O and N—H⋯N), which generate S(6) and S(5) ring motifs.
In the title compound, C 12 H 11 N 3 O 2 S, the dihedral angle between the 4H-chromen-4-one ring system and the -CH N-NH-CS-NH-unit is 6.22 (1) . In the crystal, inversion dimers linked by pairs of N-HÁ Á ÁO hydrogen bonds generate R 2 2 (14) loops. The dimers are reinforced by a pair of C-HÁ Á ÁO interactions, which generate R 2 2 (10) loops.
The title compound, C23H22N2O4S, crystallized with two independent molecules (A and B) in the asymmetric unit. They have very similar conformations with the pyrrolidine ring having a twisted conformation, on the Cspiro—Cspiro bond, in both molecules. In molecule A, the mean planes of the benzothiophene and indoline ring systems are inclined to the mean plane of the pyrrolidine ring by 87.59 (10) and 84.51 (11)°, respectively, and to one another by 72.69 (7)°. The corresponding angles in molecule B are 87.15 (10), 84.58 (10) and 72.07 (7)°, respectively. In the crystal, the A and B molecules are linked to one another by two N—H⋯O hydrogen bonds, forming a dimer. These dimers are linked via C—H⋯O hydrogen bonds, forming a three-dimensional structure.
The title compound, [ZnCl2(C8H11N)2], was synthesized by the reaction of zinc dichloride and 4-ethylaniline. The Zn2+ cation is coordinated by two Cl− anions and the N atoms of two 4-ethylaniline ligands, forming a distorted Zn(N2Cl2) tetrahedron. The dihedral angle between the two benzene rings is 85.3 (2)° The Zn atom lies on a twofold rotation axis. The ethyl substituents are disordered over two sets of sites in a 0.74 (2):0.26 (2) ratio. In the crystal, N—H⋯Cl hydrogen bonds link the molecules into sheets perpendicular to the a axis. C—H⋯Cl interactions also occur.
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.
