Abstract: In the crystal structure of the title complex, [Zn(C9H7O4)2(H2O)3]·2H2O, the Zn atom and the apical aqua ligand are located on a crystallographic twofold axis, with the ZnII ion in a distorted square-pyramidal coordination geometry composed of five O atoms, two from the monodentate methylterephthalato group and three from water molecules. The resulting complex and the two hydrate water molecules are interconnected by O-HO hydrogen bonds.
