In the title compound, Cu(C(10)H(8)O(6))(C(5)H(5)N)(2)(H(2)O), the Cu atom is five-coordinated by two O atoms from two carboxyl-ate groups of two different 2,2'-(p-phenyl-enedi-oxy)diacetate ligands, two N atoms from two pyridine mol-ecules and one water O atom. The geometry is square-pyramidal with the water O atom occupying the apical position. The carboxyl-ate group bridges adjacent Cu atoms, forming an infinite zigzag chain extending parallel to [001]. The chains are linked into layers by O-H⋯O hydrogen bonds. The Cu and water O atoms lie on special positions of site symmetry 2.
在标题化合物[Cu(C₁₀H₈O₆)(C₅H₅N)₂(H₂O)]ₙ中，铜原子由两个不同的2,2'-（对苯二氧基）二乙酸酯配体的两个羧酸根基团的两个氧原子、两个吡啶分子的两个氮原子和一个水分子的氧原子五配位。其几何构型为四方锥，水分子的氧原子占据顶端位置。羧酸根基团桥连相邻的铜原子，形成平行于[001]延伸的无限之字形链。这些链通过O-H⋯O氢键连接成层。铜原子和水分子的氧原子位于点对称2的特殊位置上。
