| 摘要: 利用1，4-二-(4-羧基吡啶基)丁烷(L)合成了两个新的三维配位聚合物{(CdL2)·4H2O·2ClO4}n 1和{(ZnL2)·4H2O·2ClO4}n 2。单晶X-射线结构分析表明，1和2具有相同的计量式，但其晶体属于不同的空间群(1属于P4n2，2属于P4222)。两种配合物中，每个金属离子分别由配体与四个相邻的金属离子连接，从而形成具有六重穿插的金刚石网络结构，其网络中大的空腔被高氯酸根离子和(H2O)4分子簇所占据。 |

| Abstract: Two novel three-dimensional coordination polymers of Zn(Ⅱ) and Cd(Ⅱ) with 1,4-bis(4-carboxypyridinium)butane (L), namely {(CdL2)·4H2O·2ClO4}n 1 and {(ZnL2)·4H2O·2ClO4}n 2, have been prepared by the reactions of Zn(ClO4)2·6H2O and Cd(ClO4)2·6H2O with L in aqueous solution, and structurally characterized. The results show that, although 1 and 2 have the same stoichiometric formula, they crystallize in different space groups with 1 in P4n2 and 2 in P4222. In both compounds, the metal atoms are each linked by L bridges to four adjacent metal centres, thus forming diamondoid networks with 6-fold penetration. The large void spaces formed in the network are filled with perchlorate anions and (H2O)4 clusters. CCDC: 1, 249252; 2, 249251. |
