In the crystal structure of the title compound, [Zn4(C8H4O4)4(C8H12N6)(H2O)4]n, one ZnII atom is four-coordinated in a slightly distorted tetrahedral geometry by two O atoms from benzene-1,3-dicarboxylate (BDC) ligands, one N atom from a 1,4-bis(1,2,4-triazol-1-yl)butane (BTB) ligand and one water molecule, while a second ZnII atom is five-coordinated in a distorted square-pyramidal geometry bridged by four O atoms from BDC ligands and one water molecule. The ZnII atoms are connected by the benzene-1,3-dicarboxylate anions and the nitrogen ligand into layers parallel to the ac plane. The asymmetric unit consits of two crystallographically independent ZnII cations, two BDC anions and two water molecules in general positions, as well as one-half of the BTB ligand that is completed by inversion symmetry.
