Abstract

The asymmetric unit of the title salt, CHN ·2Br, comprises half of the mol-ecule and a bromide ion. The chevron-shaped cations stack as columns in the [001] direction with suitable inter-molecular distance for π-π inter-actions. These cationic columns are further stabilized by inter-columnar C-H⋯N hydrogen bonding with the bromide ions distributed between them.

摘要

标题盐CHN·2Br的不对称单元由半个分子和一个溴离子组成。人字形阳离子沿[001]方向堆积成柱，分子间距离适合π-π相互作用。这些阳离子柱通过与分布在它们之间的溴离子形成柱间C-H⋯N氢键进一步稳定。
