organic compounds
The title compound, C6H6N2O2.C8H6N2O7, is composed of one molecule of p-nitroaniline and one molecule of 3,5-dinitromethyl salicylate. In this co-crystal, both the p-nitroaniline and 3,5-dinitromethyl salicylate molecules are nearly planar. These two molecules are almost coplanar with respect to each other, with a dihedral angle of 3.2 (2)° between the two aromatic ring least-squares planes. The hydroxyl group of the 3,5-dinitromethyl salicylate molecule forms an intramolecular six-membered ring hydrogen bond to the ester carbonyl O atom [H8O1 = 1.74 (4), O8O1 = 2.547 (4) Å, O8—H8O1 = 144 (3)°]. The p-nitroaniline molecules are aggregated into infinite chains by intermolecular N-HO hydrogen bonds between one of the amino protons, H1A, and one of the nitro-O atoms, O4B, of the nitroaniline molecules [H1AO4Bi = 2.22 (3), N1O4Bi = 2.984 (4) Å, N1—H1AO4Bi = 152 (3)°; symmetry code: (i) x + , − − y, − + z]. The 3,5-dinitromethyl salicylate molecules are linked to the nitroaniline chains by multiple intermolecular hydrogen bonds [O8O4B = 2.968 (3) Å, N1O8i = 3.147 (3) Å and N1O9Ai = 3.008 (4) Å].
