The 1:1 Complex Formed by 4-Nitropyridine N-Oxide and 4-Aminobenzoic Acid

The co-crystal, C₅H₄N₂O₃.C₇H₇NO₂, owes its formation to an intermolecular hydrogen bond between the N-O and O-H groups. The crystal structure exhibits overlap between the rings of the molecules in the [110] direction. There is no short nitroamino intermolecular distance.
