四氢化钕配合物[Co（NH_3）（6）]（6）-[K-2（H_2O）（10）][Nd-2（CO_3）（8）]（2）。20 H（2）O（1）的合成和表征。1的单晶X射线衍射研究揭示了九配位钕金属中心的伪一维无限链，每个中心以伪赤道方式与三个双齿碳酸酯配体络合，而第四个双齿碳酸酯基团占据每个金属上的轴向配位位点，并作为相邻链单元之间的mu（2）-eta（2），eta（1）桥。
The neodymium tetracarbonate complex [Co(NH3)(6)](6)-[K-2(H2O)(10)][Nd-2(CO3)(8)](2). 20H(2)O (1) has bt:en prepared and characterized. A single-crystal X-ray diffraction study of 1 reveals a pseudo-one-dimensional infinite chain of nine-coordinate neodymium metal centers, each complexed by three bidentate carbonate ligands in a pseudoequatorial fashion, while a fourth bidentate carbonate group occupies an axial coordination site on each metal and acts as a mu(2)-eta(2),eta(1) bridge between adjacent chain units.
