【摘要】 合成了一个新的配合物[Cd(HIDC)2·(H2O)2](H2IDC-=1H-咪唑-4,5二羧酸单阴离子),并对其进行了元素分析、IR、TG和单晶X射线的结构表征。结果表明:配合物晶体属单斜晶系,空间群为P21/n,晶胞参数为a=0.50417(10)nm,b=2.3068(5)nm,c=0.66773(13)nm,β=111.30(3)°。V=0.7235(3)nm3,Z=2,Mr=458.63,Dc=2.105g/cm3,μ=1.577mm-1,F(000)=452,最终R=0.0373,wR=0.1451。镉原子与两个不同配体H2IDC-中的咪唑上的氮原子、羧基氧原子以及水分子配位,且形成了六配位八面体构型。配合物由分子间氢键构筑成了三维超分子氢键网络结构。更多还原

【Abstract】 A novel complex of [Cd（HIDC）₂·（H₂O）₂]（H₂IDC-=1H-imidazole-4,5-dicaroxylate monoanion） was synthesized and characterized by elemental analysis, IR, TG and single crystal X-ray diffraction. The title complex crystallizes in monoclinic with space group P2₁/n, a=0.50417（10）nm, b=2.3068（5）nm, c=0.66773（13） nm,β=111.30（3）°, V=0.7235（3）nm3, Z=2, M_r=458.63, D_c=2.105 g/cm3, μ=1.577mm -1, F（000）=452, R=0.0373, wR=0.1451. Two N,O-bidentate H₂IDC-ligands and two water molecules are coordinated to cadmium（II） atom. The cadmium atom displays an octahedral coordination geometry. The 3D supramolecular hydrogen bonding network structure is constructed via the intermolecular hydrogen bond interactions.更多还原
