The title complex, [Nd(2)(C(8)H(7)O(3))(6)(C(10)H(8)N(2))(2)(H(2)O)(2)]·H(2)O, contains two Nd atoms, six 4-hy-droxy-phenyl-acetate (hpaa) anions, two 4,4'-bipyridine mol-ecules (bipy) and two water mol-ecules; an additional water mol-ecule of solvation is also present in the crystal structure. Each of the Nd(III) ions is nine-coordinated by seven O atoms from four hpaa ligands, an N atom from a bipy ligand and an O atom from a water mol-ecule in a distorted tricapped trigonal-prismatic geometry. The hpaa ligands are coordinated to the Nd(III) ions in the bridging and bridging tridentate modes. Extensive O-H⋯O, O-H⋯N and C-H⋯O hydrogen bonding stabilizes the crystal structure.
标题配合物[Nd₂(C₈H₇O₃)₆(C₁₀H₈N₂)₂(H₂O)₂]·H₂O包含两个钕原子、六个4-羟基苯乙酸（hpaa）阴离子、两个4,4'-联吡啶分子（bipy）和两个水分子；晶体结构中还存在一个额外的溶剂化水分子。每个Nd(III)离子由来自四个hpaa配体的七个O原子、来自一个bipy配体的一个N原子和来自一个水分子的一个O原子以扭曲的三帽三角棱柱几何构型进行九配位。hpaa配体以桥连和桥连三齿模式与Nd(III)离子配位。广泛的O-H⋯O、O-H⋯N和C-H⋯O氢键使晶体结构稳定。
