In the title compound, Zn(C(14)H(8)N(2)O(6))(H(2)O)(4), the 2,2'-dihydr-oxy-5,5'-diazenediyldibenzoate ligand acts as a carboxyl-ate bridge, leading to the formation of a polymeric chain running along the [10] direction. The Zn(II) atom is hexa-coordinated in a distorted octa-hedral geometry by six O atoms [Zn-O = 2.055 (4)-2.132 (3) Å] from two carboxylate ligands and four water mol-ecules. The crystal packing is stabilized by inter-molecular O-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds, and two π-π inter-actions. The centroid-centroid distances are 3.803 (16) and 3.804 (17) Å.
在标题化合物[Zn(C₁₄H₈N₂O₆)(H₂O)₄]ₙ中，2,2'-二羟基-5,5'-二氮烯二苯甲酸酯配体作为羧酸酯桥，导致形成沿[10]方向延伸的聚合物链。Zn(II)原子由来自两个羧酸酯配体的六个O原子[Zn - O = 2.055 (4)-2.132 (3) Å]和四个水分子以扭曲的八面体几何构型进行六配位。晶体堆积通过分子间的O - H⋯O、O - H⋯N和C - H⋯O氢键以及两种π - π相互作用得以稳定。质心间距为3.803 (16)和3.804 (17) Å。
