Abstract

The asymmetric unit of the title compound, C(12)H(24)N(+)·C(9)H(8)N(3)O(2) (-), consists of two dicyclo-hexyl-ammonium cations linked to two (S)-2-azido-3-phenyl-propano-ate anions by four short N-H⋯O hydrogen bonds with N⋯O distances in the range 2.712 (3)-2.765 (3) Å. The dicyclo-hexyl-ammonium cations and the aryl and carboxyl-ate groups of the anion are related by a pseudo-inversion centre, with overall crystallographic inversion symmetry for the structure broken by the chirality of the α-C atoms of the anions.

摘要

标题化合物C(12)H(24)N⁺·C(9)H(8)N(3)O(2)⁻的不对称单元由两个二环己基铵阳离子和两个(S)-2-叠氮基-3-苯基丙酸根阴离子组成，它们通过四个短的N-H⋯O氢键相连，N⋯O距离在2.712 (3)-2.765 (3) Å范围内。二环己基铵阳离子与阴离子的芳基和羧酸根基团通过一个假反演中心相关联，结构的整体晶体学反演对称性因阴离子α-C原子的手性而被打破。
