1-[2-(2,4-Dinitro-benzyl-ideneamino)phen-yl]-3-phenyl-thio-urea.

In the title compound, C(20)H(15)N(5)O(4)S, the central benzene ring makes dihedral angles of 59.5 (1) and 51.7 (1)°, respectively, with the terminal phenyl and benzene rings. The mol-ecular structure exhibits weak intra-molecular N-H⋯N and C-H⋯S inter-actions. In the crystal structure, mol-ecules are linked by weak inter-molecular N-H⋯S and C-H⋯O inter-actions, forming a chain along [11].
