In the title compound, {[Co(2)(C(16)H(6)O(8))(C(12)H(8)N(2))(H(2)O)(2)]·H(2)O}(n), one Co(II) ion has a {CoN(2)O(4)} distorted octa-hedral environment defined by two N atoms of one 1,10-phenanthroline (phen) ligand, three O atoms of the carboxyl-ate groups of three biphenyl-3,3',4,4'-tetra-carboxyl-ate (BPTC) ligands, one of which is bidentate, and one O atom from one coordinated water mol-ecule. The other Co(II) atom is surrounded by six O atoms from four different BPTC ligands and one coordinated water mol-ecule. Each BPTC ligand forms eight coordination bonds with seven Co(II) atoms, leading to a layer structure along the ac plane. Uncoordinated water mol-ecules occupy the space between the layers, and inter-act via inter-layer O-H⋯O hydrogen bonds along the b axis, generating a three-dimensional supra-molecular network.
在标题化合物{[Co₂(C₁₆H₆O₈)(C₁₂H₈N₂)(H₂O)₂]·H₂O}ₙ中，一个Co(II)离子具有由一个1,10 - 菲咯啉（phen）配体的两个N原子、三个联苯 - 3,3',4,4'-四羧酸酯（BPTC）配体的羧酸盐基团的三个O原子（其中一个为双齿）以及一个配位水分子的一个O原子所定义的{CoN₂O₄}扭曲八面体环境。另一个Co(II)原子被来自四个不同BPTC配体的六个O原子和一个配位水分子所包围。每个BPTC配体与七个Co(II)原子形成八个配位键，从而沿ac平面形成层状结构。未配位的水分子占据层间空间，并通过沿b轴的层间O - H⋯O氢键相互作用，生成三维超分子网络。
