Abstract

In the cation of the title salt, C8H11N2 (+)·Br(-), the dihedral angle between the planes of the pyridinium ring and the allyl group is 79.4 (3)°. In the crystal, N-H⋯Br and weak C-H⋯Br hydrogen bonds link the cations and anions, forming chains of alternating R 2 (1)(7) and R 4 (2)(8) rings, which run parallel to the c-axis direction. The crystal studied was an inversion twin with components in a 0.753 (12):0.247 (12) ratio.

摘要

在标题盐C8H11N2(+)·Br(-)的阳离子中，吡啶鎓环平面与烯丙基平面之间的二面角为79.4(3)°。在晶体中，N-H⋯Br和弱C-H⋯Br氢键将阳离子和阴离子连接起来，形成交替的R2(1)(7)和R4(2)(8)环链，这些环链平行于c轴方向延伸。所研究的晶体是一个倒易双晶，其组分比例为0.753(12):0.247(12)。
