The crystal structure of adenosinium 3,5‐dinitrosalicylicate, C 10 H 14 N 5 O 4 + ·C 7 H 3 N 2 O 7 − , shows the presence of a primary chain structure formed through homomeric head‐to‐tail cyclic R 2 2 (10) hydrogen‐bonding interactions between hydroxy O‐ and both purine and amine N ‐donor and acceptor groups of the furanose and purine moieties of the adenosinium species. These chain structures are related by crystallographic 2 1 symmetry. Secondary hetero‐ionic hydrogen bonding, involving the 3,5‐dinitrosalicylate anion, including a cyclic R 2 2 (8) interaction between the carboxylate group and the protonated purine and amine groups of the adenosinium cation are also present, together with heteromolecular π–π interactions giving a three‐dimensional hydrogen‐bonded polymer structure.
