In the title compound, C(6)H(18)N(2)(2+).C(4)H(4)O(4)(2-).C(4)H(6)O(4), the components lie on centres of symmetry in space group P-1, such that the asymmetric unit contains three half-molecules. Despite the different mode (with respect to other dicarboxylic acids) adopted by the intermolecular self-interaction of succinic acid derivatives, the overall structure of the title compound consists of anionic layers that are typical of the packing structures exhibited by other dicarboxylic acid analogues.
在标题化合物C₆H₁₈N₂²⁺·C₄H₄O₄²⁻·C₄H₆O₄中，各组分位于空间群P-1的对称中心上，因此不对称单元包含三个半分子。尽管琥珀酸衍生物的分子间自相互作用采用了不同的模式（相对于其他二元羧酸），但标题化合物的整体结构由阴离子层组成，这是其他二元羧酸类似物所展现的堆积结构的典型特征。
