3-Cyclohexyl-1-(3,5-dinitrobenzoyl)thiourea

The structure of the title thiourea derivative, C14H16N4O5S, features an almost planar central C2N2OS fragment (r.m.s. deviation = 0.005 ), an arrangement stabilized by an intramolecular N—H...O hydrogen bond. The terminal rings are twisted out of this plane, the dihedral angle formed with the benzene ring being 33.22 (10)°. The cyclohexyl ring is disordered, with two orientations (50:50) being resolved. The mean plane passing through the atoms of each disordered component forms dihedral angles of 65.7 (2) and 82.4 (3)° with the central plane. Centrosymmetric dimers mediated by an eight-membered {...HNC=S}2 synthon occur in the crystal.
