Abstract: In the title complex, [Zn(C₁₀H₆N₃O₂)₂(H₂O)₄], the Zn^II ion lies on an inversion center and is coordinated in a slightly distorted octahedral geometry by two N atoms from two 2-(pyridin-4-yl)pyrimidine-5-carboxylate ligands and four water molecules. In the symmetry-unique part of the molecule, the pyridine and pyrimidine rings form a dihedral angle of 7.0 (1)°. In the crystal, the coordinating water molecules act as donor groups and carboxylate O atoms act as acceptors in O-HO hydrogen bonds, forming a three-dimensional network.
