以4-(1-咪唑基)-苯甲酸(HIBA)为配体,与Cu(NO3)2·6H2O和Cd(Ac)2·2H2O在加入或不加入5-硝基间苯二甲酸(H2NPA)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(H2O)]· 3H2O]n(2)和[Cd3(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(Ⅱ)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 (H2NPA) as co-ligand result in three coordination polymers (CPs),namely,[[Cu(IBA)2] ·DMF]n (1),[[Cd(IBA)2(H2O)]· 3H2O]n (2),and [Cd3(IBA)2(NPA)2]n (3).Compounds 1 and 2 exhibit 3D 4-and 3-fold interpenetrating diamondoid frameworks,respectively.Compound 3 displays a 3D mixed-ligand framework with 1D Cdcarboxylate secondary building blocks bridged by IBA-and NPA2-ligands.The phase purity and luminescent properties of selected compounds have also been explored.
