摘要：

The structure of the title compound, C6H3N3O6.C7H7NO2, one of three co-crystalline products formed in the reaction of 2,4,6-trinitrobenzoic acid with 4-aminobenzoic acid, comprises a 1:1 adduct of 1,3,5-trinitrobenzene (TNB) and 4-aminobenzoic acid (PABA), in which both molecules are involved in homo-molecular hydrogen bonding. The PABA molecule forms an eight-membered cyclic dimer with another symmetry-generated acid molecule [O...O, 2.65 (1) Angstrom]. The TNB molecule is also involved in possible C-H...O interactions. The layered structure and red coloration of the crystals indicate possible charge-transfer interactions.
