Cytosinium 3,5-dinitrosalicylate

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

Abstract: The crystal structure of cytosinium 3,5-dinitrosalicylicate (systematic name: 6-amino-2-oxo-2,3-dihydropyrimidinium 3,5-dinitrosalicylate), C₄H₆N₃O⁺·C₇H₃N₂O₇^-, shows the presence of a primary heteroionic cyclic R₂²(8) interaction between the H-atom donors of the protonated cytosinium cation and the carboxylate O-atom acceptors of the 3,5-dinitrosalicylate anion. Additional peripheral hydrogen-bonding interactions involving all available cytosinium H-atom donors and both phenol and nitro O-atom acceptors of the anion species give a three-dimensional polymeric structure.
