In the title compound, Ni(C(14)H(8)O(4))(C(10)H(8)N(2))(H(2)O)(2), the Ni(II) atom is coordinated in a slightly distorted octa-hedral geometry by two water mol-ecules, two N atoms from a 2,2'-bipyridine ligand and two O atoms from the carboxyl-ate groups of two 2,2'-biphenyl-dicarboxyl-ate (2,2'-dpa) ligands. The 2,2'-dpa ligand acts as a bridge between neighbouring Ni(II) atoms, forming one-dimensional coordination polymers along [100]. The coordinated water mol-ecules form hydrogen bonds to the carboxyl-ate O atoms of 2,2'-dpa within the same coordination polymer, and one O-H⋯π inter-action is also formed to 2,2'-dpa.
在标题化合物[Ni(C₁₄H₈O₄)(C₁₀H₈N₂)(H₂O)₂]ₙ中，Ni(II)原子由两个水分子、来自一个2,2'-联吡啶配体的两个N原子以及来自两个2,2'-联苯二甲酸酯（2,2'-dpa）配体的羧酸根基团的两个O原子以稍有畸变的八面体几何构型配位。2,2'-dpa配体作为相邻Ni(II)原子之间的桥连，沿[100]方向形成一维配位聚合物。配位水分子与同一配位聚合物内2,2'-dpa的羧酸根O原子形成氢键，并且还与2,2'-dpa形成一个O—H⋯π相互作用。
