Abstract
The asymmetric unit of the title compound, C6H5N3O, consists of discrete molecules of 9-deazahypoxanthine [systematic name: 3H-pyrrolo[3,2-d]pyrimidin-4(5H)-one]. The structure displays N—H...O hydrogen bonding, connecting the molecules into centrosymmetric dimers. These dimers are then connected by N—H...N hydrogen bonds into a ladder-like chain along thecaxis. The secondary structure is stabilized by weak noncovalent contacts of the C—H...O and C—H...C types, as well as by π–π stacking interactions, which organize the structure into a zigzag architecture.
