N-(2,4-Dinitrophenyl)-N′-[nitro(phenyl)methylene]hydrazine
نویسنده
چکیده
The title compound, C(13)H(9)N(5)O(6), contains three nitro groups. It is prepared by the reaction of benzaldehyde 2,4-dinitro-phenyl-hydrazone with nitric oxide at ambient temperature. The imine group is nearly coplanar with the (2,4-dinitro-phen-yl)-hydrazine unit. The second benzene ring and the third nitro group are twisted away from this plane, with dihedral angles of 48.5 (3) and 15.2 (3)°, respectively. Weak intra-molecular N-H⋯O inter-actions are observed.
