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,12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。

关 键 词:非中心对称金刚石网络结构; 1,4-二-(4-羧基吡啶基)丁烷; Cd(Ⅱ)配位化合物; Zn(Ⅱ)配位化合物

Abstract:Two novel three-dimensional coordination polymers of Zn(Ⅱ) and Cd(Ⅱ) with 1,4-bis(4-carboxypyridinishow 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.
Keywords:acentric diamondoid net  1,4-bis(4-carboxypyridinium)butane  Cd(Ⅱ) coordination polymer  Zn(Ⅱ) coordination polymer
