The dinuclear title complex, [Co(2)(C(15)H(8)O(7))(2)(H(2)O)(6)], lies across an inversion center. The unique Co(II) ion is coordinated in a slightly distorted octa-hedral coordination geometry by two O atoms from a chelating 4-(carb-oxy-phen-oxy)phthalate ligand, three water O atoms and a further O atom from a bridging carboxyl-ate group of a symmetry-related 4-(carb-oxy-phen-oxy)phthalate ligand. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
双核标题配合物[Co₂(C₁₅H₈O₇)₂(H₂O)₆]位于一个对称中心上。独特的Co(II)离子通过来自螯合的4-(羧基苯氧基)邻苯二甲酸酯配体的两个O原子、三个水分子O原子以及来自一个对称相关的4-(羧基苯氧基)邻苯二甲酸酯配体的桥连羧酸根基团的另一个O原子,以稍有畸变的八面体配位几何构型配位。在晶体中,O—H⋯O氢键将分子连接成三维网络。
