Adenosinium 3,5-dinitrosalicylate

G. Smith, U. D. Wermuth and P. C. Healy

Abstract: The crystal structure of adenosinium 3,5-dinitrosalicylicate, C₁₀H₁₄N₅O₄⁺·C₇H₃N₂O₇^-, shows the presence of a primary chain structure formed through homomeric head-to-tail cyclic R₂²(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 2₁ symmetry. Secondary hetero-ionic hydrogen bonding, involving the 3,5-dinitrosalicylate anion, including a cyclic R₂²(8) interaction between the carboxylate group and the protonated purine and amine groups of the adenosinium cation are also present, together with heteromolecular - interactions giving a three-dimensional hydrogen-bonded polymer structure.
