In the title complex, [Zn(C(7)H(5)O(3))(2)(C(10)H(8)N(2))(H(2)O)], the Zn(II) ion is coordinated by two 4-hydroxy-benzoate anions, one 2,2'-bipyridine mol-ecule and one water mol-ecule and displays a distorted octa-hedral geometry. One Zn-O bond [2.5300 (15) Å] is much longer than the others in the mol-ecule. 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.
在标题配合物[Zn(C₇H₅O₃)₂(C₁₀H₈N₂)(H₂O)]中，Zn(II)离子由两个4-羟基苯甲酸根阴离子、一个2,2'-联吡啶分子和一个水分子配位，呈现出扭曲的八面体几何构型。分子中的一条Zn - O键[2.5300 (15) Å]比其他键长得多。在晶体结构中，面对面间距为3.547 (9) Å，表明平行的联吡啶环系统之间不存在π - π堆积，并且在配位水分子、酚基和羧酸根O原子之间存在广泛的O - H⋯O氢键网络。
