In the title solvate, C(11)H(11)N(3)O(2)S·CH(3)NO(2), the dihedral angle between the benzene ring and the N-containing ring is 85.94 (11)°, and an approximate V shape arises for the sulfonamide mol-ecule. In the crystal, N-H⋯O and N-H⋯N hydrogen bonds and weak C-H⋯O inter-actions link the sulfonamide mol-ecules into a three-dimensional network. The nitro-methane solvent mol-ecules are located i...

The crystal structure of the title compound, [Ru(C(10)H(15))(C(7)H(9)NO(2)S)]C(24)H(20)B, has been determined as part of our investigation into the structural and biological properties of organometallic Ru(II)-arene-Cp* complex salts of the type [R-PhRuCp*](+)·X(-) (where Cp* is penta-methyl-cyclo-penta-diene). Tethering the RuCp* group to the benzene ring of p-toluene-sulfonamide results in on...

The crystal structures of three isomeric compounds of formula C14H13Cl2NO2S, namely 3,5-di-chloro-N-(2,3-di-methyl-phen-yl)-benzene-sulfonamide (I), 3,5-di-chloro-N-(2,6-di-methyl-phen-yl)benzene-sulfonamide (II) and 3,5-di-chloro-N-(3,5-di-methyl-phen-yl)benzene-sulfonamide (III) are described. The mol-ecules of all the three compounds are U-shaped with the two aromatic rings inclined at 41.3 ...

In the title compound, C17H17N3O3 (.)0.5H2O, the indazole system makes a dihedral angle of 46.19 (8)° with the plane through the benzene ring and is nearly perpendicular to the allyl group, as indicated by the dihedral angle of 81.2 (3)°. In the crystal, the water mol-ecule, disordered over two sites related by an inversion center, forms O-H⋯N bridges between indazole N atoms of two sulfonamide...

The title compound, C(13)H(19)NO(2)S, was synthesized by the reaction of N-cyclo-hexyl-amine-benzene-sulfonamide and methyl iodide. The crystal packing is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

In the title compound, C14H13N3O3S, the fused ring system is almost planar, the largest deviation from the mean plane being 0.023 (2) Å, and makes a dihedral angle of 47.92 (10)° with the benzene ring of the benzene-sulfonamide moiety. In the crystal, mol-ecules are connected through N-H⋯O hydrogen bonds and weak C-H⋯O contacts, forming a two-dimensional network which is parallel to (010).

The asymmetric unit of the title compound, C17H17N3O2S, contains two independent mol-ecules linked by an N-H⋯O hydrogen bond. The mol-ecules show different conformations. In the first mol-ecule, the fused five- and six-membered ring system is almost perpendicular to the plane through the atoms forming the allyl group, as indicated by the dihedral angle of 85.1 (4)°. The dihedral angle with the ...

In the title compound, C(13)H(13)NO(2)S, the conformation of the N-H bond is anti to the ortho-methyl group on the aniline ring, in contrast to the syn conformation observed with respect to the ortho-chloro group in N-(2-chloro-phen-yl)benzene-sulfonamide. The dihedral angle between the two benzene rings is 61.5 (1)°. Mol-ecules are linked into chains running along the a axis by N-H⋯O hydrogen ...

In the title compound, C15H15N3O2S, the fused ring system is close to planar, the largest deviation from the mean plane being 0.030 (2) Å, and makes a dihedral angle of 48.84 (9)° with the benzene ring belonging to the methyl-benzene-sulfonamide moiety. In the crystal, mol-ecules are -connected through N-H⋯N hydrogen bonds and weak C-H⋯O contacts, forming a two-dimensional network parallel to (...

In the title compound, C(14)H(10)F(3)N(3)O(3)S, there are significant twists in the mol-ecule, as seen in the values of the dihedral angles between the pyrazole ring and each of the furan [31.1 (2)°] and benzene rings [55.58 (10)°]. The amino N atom occupies a position almost normal to the benzene ring [N-S-C(ar)-C(ar) (ar = aromatic) torsion angle = 83.70 (19)°]. One amino H atom forms a hydro...
