| Summary: | In the title complex, [Zn(C7H5O3)2(C10H8N2)(H2O)], the ZnII ion is coordinated by two 4-hydroxybenzoate anions, one 2,2′-bipyridine molecule and one water molecule and displays a distorted octahedral geometry. One Zn—O bond [2.5300 (15) Å] is much longer than the others in the molecule. In the crystal structure, the face-to-face separation of 3.547 (9) Å suggests no π–π stacking between parallel bipyridine ring systems, and an extensive O—H...O hydrogen-bonding network between the coordinated water molecule, the phenol group and carboxylate O atoms is present.
