In the title compound, [Zn(C(10)H(5)O(4))(2)(H(2)O)(2)], the Zn(II) atom lies on a crystallographic inversion center and is six-coordinated by two O atoms from water mol-ecules in the axial positions and four O atoms from two deprotonated coumarin-3-carb-oxy-late ligands in the equatorial plane, forming a slightly distorted octa-hedral coordination geometry. O-H⋯O hydrogen-bonding inter-actions involving the water mol-ecules form infinite chains parallel to [010].
在标题化合物[Zn(C₁₀H₅O₄)₂(H₂O)₂]中，Zn(II)原子位于一个晶体学反演中心，在轴向位置由两个水分子中的O原子六配位，在赤道平面由两个去质子化的香豆素-3-羧酸根配体中的四个O原子六配位，形成一个轻微扭曲的八面体配位几何结构。涉及水分子的O—H⋯O氢键相互作用形成平行于[010]的无限链。
