The title compound, C13H14N5O+.Cl-, belongs to the group of aromatic cytokinins. These compounds affect a variety of important physiological processes in plants and animals as well as in bacteria, including cell division, differentiation and senescence. The structure consists of a 6-(4-methoxybenzylamino)purinium cation and a Cl- anion. The cation moiety exists as the N3-protonated N7 tautomer. The cation contains nearly planar benzene and purine ring systems, with a dihedral angle of 77.46 (5) degrees. The crystal structure is stabilized by N(amino)-H...N(purine) hydrogen bonds connecting two adjacent molecules, thus forming centrosymmetric dimers.
