Abstract Crystals of 9-methyladenine salicylate (C6H8N 5 + ·C7H5O 3 − ), mp 126°C, are orthorhombic, space groupPbcn (D 2h 14 , No. 60) witha=25.305(3),b=8.066(1),c=12.928(2) Å,d c=1.446 g cm−3,d m=1.43 g cm−3 (CCl4/ cyclohexane) forZ=8. The 9-methyladenine, protonated at N(1), and salicylate form a pair of strong hydrogen bonds with N⋯O distances of 2.617 and 2.858 Å. In addition, a hydrogen bond is formed between two adenine moieties using the amino group and imidazole nitrogen, N(7), with N⋯N separation of 3.114 Å. As in salicylic acid, an intermolecular hydrogen bond of 2.560 Å is formed between the hydroxyl and a carboxyl oxygen atoms.
