The reaction of 1,2-bis-{2-[(2-hydroxy-ethyl)amino-methyl]-phen-oxy}ethane and fumaric acid in a mixed solution in ethanol-water (1:1 v/v) yields the title compound, C(20)H(30)N(2)O(4) (2+)·C(4)H(2)O(4) (2-)·4H(2)O. In the crystal structure, the anions, cations and water mol-ecules are connected via O-H⋯O and N-H⋯O hydrogen bonds into a three-dimensional network. The fumarate anion and the N,N'-bis-(2-hydroxy-ethyl)-N,N'-[ethyl-enedioxy-bis(o-phenyl-enemethylene)]diammonium cation are located on centers of inversion, whereas the two crystallographically independent water mol-ecules occupy general positions.
1,2-双-{2-[(2-羟乙基)氨基甲基]苯氧基}乙烷与富马酸在乙醇-水（1:1 v/v）混合溶液中反应生成标题化合物C(20)H(30)N(2)O(4) (2+)·C(4)H(2)O(4) (2-)·4H(2)O。在晶体结构中，阴离子、阳离子和水分子通过O-H⋯O和N-H⋯O氢键连接成三维网络。富马酸根阴离子和N,N'-双-(2-羟乙基)-N,N'-[乙二氧基双(邻苯基亚甲基)]二铵阳离子位于对称中心，而两个晶体学独立的水分子占据一般位置。
