The asymmetric unit of the title mol-ecular salt [systematic name: 1,4,8,11-tetraazacyclotetradecane-1,8-diium bis(3-carboxy-prop-2-enoate)], C10H26N4 (2+)·2C4H3O4 (-), contains two half-cations (both completed by crystallographic inversion symmetry) and two maleate anions. The cyclam macrocycles adopt trans-III conformations, supported by two intra-molecular N-H⋯O hydrogen bonds. The O-bonded H atom of each maleate ion is disordered over two positions with an occupancy ratio of 0.61 (5):0.39 (5): each one generates an intra-molecular O-H⋯O hydrogen bond. In the crystal, the cations are linked to the anions by N-H⋯O hydrogen bonds, generating [001] chains.
标题分子盐[系统名称：1,4,8,11-四氮杂环十四烷-1,8-二铵双(3-羧基-2-烯酸酯)]，C₁₀H₂₆N₄(2+)·2C₄H₃O₄(-)的不对称单元包含两个半阳离子（均通过晶体学倒转对称性完成）和两个马来酸根阴离子。环胺大环采取反式-III构象，由两个分子内N-H⋯O氢键支撑。每个马来酸根离子的O键合H原子在两个位置上无序，占有率比为0.61 (5):0.39 (5)，每个位置都形成一个分子内O-H⋯O氢键。在晶体中，阳离子通过N-H⋯O氢键与阴离子相连，形成[001]链。
