Ethane-12-diaminium 22′-tereph­thal­oyl­bis(aza­nedi­yl)di­acetate tetrahydrate

摘要

In the title salt hydrate, C2H10N2 ²⁺·C12H10N2O6 ²⁻·4H2O, each of the ions is located about a centre of inversion and the asymmetric unit is completed by two water molecules in general positons. In the crystal, the cations, anions and water mol­ecules are connected by O—H⋯O and N—H⋯O hydrogen bonding into a three-dimensional network.
