以稀土氧化物、异烟酸、氯化铜和碘化钾为原料，水热合成了四种三维异金属配位聚合物[Ln 2Cu 4 I3（IN）7（H2O）]n（1，2）和[LnCu3.5I3（IN）3.5（H2O）3]n·nH 2 O（3，4）[HIN =异烟酸，Ln = Nd（1），Gd（2），La（3），Eu（4）]。原料的不同摩尔比导致化合物1-4的两种不同类型的三维骨架。化合物1和2的结构由[Ln 2（IN）7（H2O）]nn-和Cu 4 I3簇合物的层模块构成，而化合物3和4的结构由二聚的Ln 2（IN）6（H2O）6和层状聚合的[Cu 7I 6]nn+单元构成。
Four three-dimensional heterometallic coordination polymers, [Ln2Cu4I3(IN)7(H2O)]n (1, 2) and [LnCu3.5I3(IN)3.5(H2O)3]n·nH2O (3, 4) [HIN = isonicotinic acid, Ln = Nd (1), Gd (2), La (3), Eu (4)] were hydrothermally synthesized by using lanthanide oxides, isonicotinic acid, copper chloride, and potassium iodide. The different molar ratio of raw materials results in two distinct types of three-dimensional frameworks of compounds 1–4. The structure of compounds 1 and 2 are constructed by the layer modules of [Ln2(IN)7(H2O)]nn– and Cu4I3 clusters, whereas that of compounds 3 and 4 are built by dimeric Ln2(IN)6(H2O)6 and layered polymeric [Cu7I6]nn+ units.
