Abstract

The title mol-ecular salt, C8H13N2 (+)·Br(-), crystallizes with two independent 3-amino-pyridinium cations and two bromide anions in the asymmetric unit (Z' = 2). In the pyridine ring, the N atom is alkyl-ated by a propyl group. The dihedral angle between the mean planes of the pyridinium ring and the propyl group is 84.84 (2)° in cation A, whereas the corresponding angle is 89.23 (2)° in cation B. In the crystal, the anions and cations are linked via N-H⋯Br and C-H⋯Br hydrogen bonds, forming chains propagating along [100].

3-氨基-1-丙基溴化吡啶的晶体结构。

命名盐C8H13N2(+)·Br(-)在不对称单元(Z′= 2)上与两个独立的3-氨基吡啶阳离子和两个溴离子结晶。在吡啶环上，N原子被一个丙基烷基化。在阳离子A中，吡啶环和丙基的平均平面之间的二面角为84.84(2)°，而在阳离子b中，相应的角度为89.23(2)°。在晶体中，阴离子和阳离子通过N-H⋯Br和C-H⋯Br氢键连接，形成沿[100]传播的链。
