Abstract

In title compound, C12H9IN2O2S, the nitro group is rotated slightly, by 8.91 (3)°, out of the plane of the aromatic ring to which it is bonded. Between the two aromatic rings the CSN plane is at a dihedral angle of 84.0 (7)° to the HNC plane. Mol-ecules are linked by C - H⋯O inter-actions into a double helical supra-molecular architecture. There are no iodo-nitro, π-π or C - H⋯π(arene) inter-actions.
