N-(Diethyl-carbamothio-yl)-4-nitro-benzamide.

In the title compound, C(12)H(15)N(3)O(3)S, the 4-nitro and carbonyl groups are nearly coplanar with the benzene ring [C-C-N-O = -175.72 (14) and C-C-C-O = 172.75 (14)°]. The diethyl-carbamothioyl group is twisted significantly from the plane of the benzene ring [C-N-C-N = -89.79 (15)°] with the S atom pointing away from each of these groups [C-N-C-S = 91.12 (14)°]. In the crystal, an inter-molecular N-H⋯O hydrogen bond, which forms an infinite polymeric chain along the c axis, and weak C-H⋯O and C-H⋯S hydrogen bonds are observed.
