In the title coordination polymer, {[Gd(C(12)H(8)NO(2))(3)(H(2)O)(2)]·H(2)O}(n), the Gd(III) ion is ligated by one bidentate carboxyl-ate group, four monodentate bridging carboxyl-ate O atoms and two water mol-ecules. The resulting GdO(8) polyhedron approximates to a square anti-prism. The bridging ligands link the metal ions into a [100] chain, with each pair of adjacent metal ions being bridged by two ligands. Inter-chain O-H⋯O and O-H⋯N hydrogen bonds help to establish the packing.
在标题配位聚合物{[Gd(C₁₂H₈NO₂)₃(H₂O)₂]·H₂O}ₙ中，Gd(III)离子由一个双齿羧酸根基团、四个单齿桥连羧酸根O原子和两个水分子配位。所得的GdO₈多面体近似于一个方形反棱柱。桥连配体将金属离子连接成一条[100]链，每对相邻金属离子由两个配体桥连。链间的O—H⋯O和O—H⋯N氢键有助于形成堆积结构。
