In the crystal of the title mol-ecular salt, C(7)H(7)N(2) (+)·Br(-), the cations form inversion dimers via weak pairwise C-H⋯N hydrogen bonds; their mean planes are separated by 0.292 (6) Å. Weak C-H⋯Br inter-actions involving all of the remaining H atoms tie the cations and anions together into sets of inter-penetrating sheets. The title compound is isostructural with its iodide analogue.
在标题分子盐C(7)H(7)N(2) (+)·Br(-)的晶体中，阳离子通过弱的成对C-H⋯N氢键形成反演二聚体；它们的平均平面相距0.292 (6) Å。涉及所有其余H原子的弱C-H⋯Br相互作用将阳离子和阴离子连接在一起形成相互贯穿的片层集合。标题化合物与其碘化物类似物同构。
