Notes:
In the crystal structure of the proton-transfer complex of (8-quinolinyl)urea (QUR) with 3,5-dinitrosalicylic acid (DNSA), 8-ureidoquinolinium 3,5-dinitrosalicylate, [(QUR)+ (DNSA)−] or C10H10N3O+·C7H3N2O7−, the hetero–N atom of QUR is protonated and, together with all urea protons, is involved in extensive hydrogen-bonding associations which result in a three-dimensional network polymer [N...O 2.711–3.251 (2) Å]. In addition, the quinolinium proton is involved in an intramolecular hydrogen bond with a urea–N atom [N—N 2.841 (2) Å] and within the DNSA anions a short intramolecular O(carboxyl)...O(hydroxy) hydrogen bond is also present [O...O 2.492 (2) Å].
