چکیده
The title compound, C(9)H(10)N(4)O(2)S, was prepared by the reaction of 1-(4-nitro-phen-yl)ethanone and thio-semicarbazide in ethanol at 367 K. There are weak inter-molecular N-H⋯S and N-H⋯O hydrogen-bonding inter-actions in the crystal structure involving the amine and nitrile groups, respectively, as donors.

In the title compound, C(17)H(18)BrN(3)O(2)S, the dihedral angle between the aromatic rings is 9.15 (17)°. A bifurcated intra-molecular N-H⋯(N,O) hydrogen bond generates two S(5) rings and a weak intra-molecular C-H⋯S inter-action completes an S(6) ring motif. In the crystal, inversion dimers linked by pairs of N-H⋯S hydrogen bonds generate R(2) (2)(8) loops and weak C-H⋯S and C-H⋯π inter-actio...
