Abstract: The title compound, C13H13N5O, consists of discrete molecules connected by N-H
N hydrogen bonds to form infinite chains, with N
N separations of 3.0379 (15) and 2.8853 (15) Å. The benzene and purine ring systems make a dihedral angle of 77.58 (3)°. The crystal structure is further stabilized by intramolecular N
O interactions [2.9541 (12) Å] and intermolecular C-H
C and C
C contacts [3.304 (2), 3.368 (2), 3.667 (2), 3.618 (2) and 3.512 (2) Å] which arrange the molecules into graphite-like layers. The interlayer separations are 3.248 and 3.256 Å.
