N6-benzyladenine hydrobromide and the solid-state conformation of cytokinins

In the title compound, N-6-benzyladenine hydrobromide [N-6-benzyladeninium bromide], C12H12N5+. Br-, the adenine moiety exists as the N3-protonated N7-H tautomer. The N6 substituent is distal to N7 and the phenyl ring makes a dihedral angle of 108.43 (12)degrees with the adenine plane. Thus, protonation of benzyladenine does not affect the conformational requirements for cytokinin activity. The conformation of the title compound has been compared with other cytokinins.
