Abstract: In the title compound, {[Zn₂(C₁₆H₄I₂O₈)(H₂O)₄]·2H₂O}_n, two crystallographically independent Zn^II atoms are each located on a twofold rotation axis. Both Zn^II atoms are in distorted octahedral coordination geometries: one is coordinated by six O atoms from four carboxylate groups, while the other is coordinated by two carboxylate groups and four water molecules. The tetracarboxylate ligand molecules connect the Zn^II atoms, completing a three-dimensional metal-organic framework. O-HO hydrogen bonds link the metal-organic framework with the uncoordinated water molecules.
