The perpendicular distance between the planes of successive molecules of 8-azaguanine, in crystals of 8-azaguanine monohydrate, is 3.25 Å. This distance indicates intermolecular interaction of the charge-transfer type. 8-Azaguanine may act as a cell poison by forming a charge-transfer complex within the bacterial RNA.
