N-(7-Eth-oxy-1H-indazol-4-yl)-4-methyl-benzene-sulfonamide
Abstract:
The mol-ecule of the title heterocyclic compound, C(16)H(17)N(3)O(3)S, is bent at the S atom with an C-SO(2)-NH-C torsion angle of 80.17 (8)°. The phenyl substituent at the S atom is rotated out of the plane of the 1H-indazole ring [inter-planar angle = 46.24 (8)°]. In the crystal, inter-molecular N-H⋯N and N-H⋯O hydrogen bonds build up a ribbon developing parallel to the b-axis direction. C-H⋯O hydrogen bonds link these ribbons, forming a layer parallel to the bc plane.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
