Abstract:
In the title compound (systematic name: 6-benzylamino-7H-purin-3-ium p-toluenesulfonate), C(12)H(12)N(5)(+)·C(7)H(7)O(3)S(-), the adenine moiety exists as the N(3)-protonated N(7)-H tautomer. The dihedral angle between the adenine ring system and the phenyl ring is 82.76 (11)°. Two of the sulfonate O atoms form C-H···O and N-H···O hydrogen bonds with the H atoms on the N and C atoms in the 3- and 8-positions, respectively, of the adenine moiety, leading to a zigzag chain. Two antiparallel zigzag chains are linked by the remaining sulfonate O atom through Hoogsteen-site H atoms (i.e. those on the N atoms in the 6- and 7-positions) of the adenine moiety, leading to a double chain. An annulus formed by a pair of inversion-related anions and cations has been identified. An intramolecular toluenesulfonate-phenyl C-H···π interaction is also present.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
