title: 3-(3-Amino-phenyl-sulfon-yl)aniline.
abstract: In the title compound, C(12)H(12)N(2)O(2)S, the aromatic rings are oriented at a dihedral angle of 79.48 (4)°. Intra-molecular C-H⋯O hydrogen bonds result in the formation of two five-membered rings with envelope conformations. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules. π-π Contacts between the benzene rings, [centroid-centroid distance = 4.211 (3) Å] may further stabilize the structure.
