title: Bis(3-amino-phen-yl) sulfone acetonitrile solvate.
abstract: In the sulfone mol-ecule of the title compound, C(12)H(12)N(2)O(2)S·C(2)H(3)N, the two benzene rings are oriented at a dihedral angle of 80.69 (3)°. Weak intra-molecular C-H⋯O hydrogen bonds result in the formation of two five-membered rings, which both have envelope conformations. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules.
