In the crystal structure of the title compound, C(7)H(7)N(2) (+)·I(-), the cations form inversion-related dimers via weak pairwise C-H⋯N hydrogen bonds. In the dimers, the pyridinium rings are parallel to one another with their mean planes separated by a normal distance of ca 0.28 Å. Weak C-H⋯N inter-actions between adjacent dimers generate a layer lying parallel to (10-1). The remaining H atoms form C-H⋯I inter-actions, which link the layers into a three-dimensional structure.
在标题化合物C₇H₇N₂⁺·I⁻的晶体结构中，阳离子通过弱的成对C-H⋯N氢键形成与反演相关的二聚体。在二聚体中，吡啶鎓环彼此平行，其平均平面之间的垂直距离约为0.28 Å。相邻二聚体之间的弱C-H⋯N相互作用产生一个平行于(10-1)的层。其余的H原子形成C-H⋯I相互作用，将这些层连接成三维结构。
