以4，5-咪唑二元酸(IMDC)和2-乙基-4，5-咪唑二元酸(2-EtIMDC)为有机配体，水热合成了两个新的金属有机骨架[Cd3(H2O)2(C5N2O4H)2·H2O]1和[KCd(C7N2O4H5)]2。单晶结构分析表明，化合物1具有三维骨架，它是由沿c轴方向的一维链柱撑而成的二维层形成的。化合物2是一个具有一维通道的三维结构，这些通道由[CdN2O]三角双锥单元和2-EtIMDC配体以十字形方式连接。
Two new metal–organic frameworks [Cd3(H2O)2(C5N2O4H)2·H2O] 1 and [KCd(C7N2O4H5)] 2 have been hydrothermally synthesized employing 4,5-imidazoledicarboxylic acid (IMDC) and 2-ethyl-4,5-imidazoledicarboxylic acid (2-EtIMDC) as organic ligands. The single-crystal structure analysis reveals that compound 1 exhibits a 3-D framework, which is generated from 2-D layers pillared by 1-D chains along the c-axis. Compound 2 presents a 3-D structure with 1-D channels, which are connected in a cross-like fashion by [CdN2O3] trigonal bipyramid units and 2-EtIMDC ligands.
