Abstract: In the title compound, C26H30ClN5O·CHCl3, the purine molecule consists of essentially planar benzene and purine ring systems [maximum deviation 0.010 (4) Å for both ring systems] forming a dihedral angle of 85.52 (9)°. Intermolecular N-H
N hydrogen bonds link adjacent molecules into centrosymmetric dimers. The structure also contains intermolecular C-H
O and C-H
N interactions. The benzene rings form offset face-to-face
-
stacking interactions with an interplanar distance of 3.541 (4) Å and a centroid-to-centroid distance of 4.022 (4) Å.
