The title compound {systematic name: trimethyl[2-({4-oxo-4-[2-(trimethylazaniumyl)ethoxy]butanoyl}oxy)ethyl]azanium diiodide}, C(14)H(30)N(2)O(4)(2+)·2I(-), is a salt of the succinylcholinium cation. There is one formula unit in the asymmetric unit, represented by two anions and two halves of two cations which lie on centres of inversion. The component species are stabilized by electrostatic interactions, and C-H···I and C-H···O hydrogen bonds are also present.
标题化合物{系统名称：三甲基[2-({4-氧代-4-[2-(三甲基铵基)乙氧基]丁酰基}氧基)乙基]铵二碘化物}，C(14)H(30)N(2)O(4)(2+)·2I(-)，是琥珀酰胆碱阳离子的一种盐。不对称单元中有一个化学式单元，由两个阴离子和位于对称中心的两个阳离子的两个半部分表示。各组成物种通过静电相互作用得以稳定，同时还存在C-H···I和C-H···O氢键。
