摘要
以4-(1-咪唑基)-苯甲酸(HIBA)为配体,与Cu(NO_3)2·6H_2O和Cd(Ac)_2·2H_2O在加入或不加入5-硝基间苯二甲酸(H_2NPA)的情况下,通过水热法得到了3个新的配位聚合物,分别为{[Cu(IBA)_2]·DMF}n(1)、{[Cd(IBA)2(H_2O)]·3H_2O}n(2)和[Cd_3(IBA)_2(NPA)_2]n(3)。配合物1和2分别为4重和3重穿插的具有金刚石拓扑网络的三维框架结构,配合物3是由混合配体形成的基于一维Cd-羧基次级构筑基元的三维框架结构,其一维构筑基元由Cd髤离子通过IBA-和NPA2-配体同时桥联形成的。此外,还表征了这些化合物的晶相纯度以及配合物2和3的荧光性质。
Reactions of Cu (Ⅱ) or Cd (Ⅱ) salts, 4-(imidazol-1-yl)-benzoic acid(HIBA) with or without 5-nitroisophthalic acid(H_2 NPA) as co-ligand result in three coordination polymers(CPs), namely, {[Cu(IBA)_2]·DMF}n(1),{[Cd(IBA)_2(H_2O)]·3 H_2 O}n(2), and [Cd_3(IBA)_2(NPA)_2]n(3). Compounds 1 and 2 exhibit 3D 4-and 3-fold interpenetrating diamondoid frameworks, respectively. Compound 3 displays a 3 D mixed-ligand framework with 1 D Cdcarboxylate secondary building blocks bridged by IBA-and NPA2-ligands. The phase purity and luminescent properties of selected compounds have also been explored. CCDC: 1554061, 1; 1554062, 2; 1554063, 3.
