Abstract: In the title compound, {[Zn(C₁₀H₂O₈)(C₃H₁₂N₂)]·4H₂O}_n, the Zn²⁺ ions are in a distorted tetrahedral environment made up of four O atoms from four benzene-1,2,4,5-tetracarboxylate anions, which leads to the formation of a polymeric three-dimensional network. The disordered (3:1) propane-1,2-diammonium counter-cations and the water molecules are located in the voids of the network. Intermolecular N-HO and O-HO hydrogen bonds help to consolidate the crystal packing.
