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.
标题化合物 C6H5N3O 的不对称单元由 9-deazahypoxanthine [系统名称:3H-pyrrolo[3,2-d]pyrimidin-4(5H)-one] 的离散分子组成。该结构显示出 N-H...O 氢键,将分子连接成中心对称的二聚体。然后,这些二聚体通过 N-H...N 氢键沿轴向连接成阶梯状链。二级结构通过 C-H...O 和 C-H...C 两种类型的弱非共价接触以及 π-π 堆积相互作用而得到稳定,从而将结构组织成人字形结构。
