| Summary: | In the title compound, {[Zn2(C12H12O4)2(C11H10N4O)(H2O)]·3H2O}n, monoperiodic coordination polymer double strands are held into the triperiodic crystal structure by means of N—H...O hydrogen-bonding patterns between the amide groups of the 1,3-di(pyridin-4-yl)urea ligands and unligated O atoms belonging to 5-tert-butylisophthalate ligands. One of the Zn atoms displays a tetrahedral coordination environment, while the other Zn atom adopts a five-coordinate geometry intermediate between square pyramidal and trigonal bipyramidal. Additionally, O—H...O hydrogen-bonding patterns involving the water molecules of crystallization serve as a structure-stabilizing element by aggregating the double-strand motifs.
