The crystal structure of dicyclohexylamnium 4‐nitroanthranilate, C 12 H 24 N + ·C 7 H 5 N 2 O 4 − , shows a three‐dimensional hydrogen‐bonded network polymer in which the protonated amine groups of both of the independent molecules of dicyclohexylamine give similar hydrogen‐bonding interactions with oxygen acceptors of four separate anthranilate carboxylate groups [N⋯O = 2.730 (3)–2.782 (2) Å]. Secondary centrosymmetric peripheral hydrogen‐bonding linkages involve the amine groups of the anthranilate anions with nitro and carboxylate O‐atom acceptors, while these groups are also involved in intramolecular N—H⋯O(carboxylate) associations [2.663 (3) and 2.679 (3) Å].
