| 摘要: 以二氰胺钠[Na(dca)]和4-(1-咪唑基)苯胺(L)为共配体分别与锰盐和钴盐反应合成了2种新的配合物：零维[Mn(L)2(dca)2(H2O)2] (1)和二维[Co(L)2(dca)](dca)0.5(ClO4)0.5·1.5H2O·MeOH (2)。通过元素分析、红外光谱和X射线单晶衍射对其进行了表征。配合物1属于三斜晶系，P1空间群。配合物2晶体属于正交晶系，Cmcm空间群。配合物1是1个中心对称的单核结构，锰(Ⅱ)离子与分别来自2个dca和2个L配体的4个氮原子以及2个水分子配位，形成八面体配位几何，L和dca均为单齿配位；配合物2是由混合桥dca和L组装成的二维配位聚合物网状结构，相邻的二维网以面对面方式堆积，沿c轴方向形成一维孔道，里面填充着未配位的反离子和溶剂分子。 |

| Abstract: Reactions of sodium dicyanamide (Na(dca)) and 4-(1H-Imidazol-1-yl)aniline (L) with MnCl2·4H2O or CoCl2·6H2O generate two new complexes, 0D [Mn(L)2(dca)2(H2O)2] (1) and 2D coordination polymer of [Co(L)2(dca)](dca)0.5(ClO4)0.5·1.5H2O·MeOH (2), which were characterized by elemental analysis and IR. X-ray crystal strucatural analyses show that 1 crystallizes in triclinic space group P1, 2 crystallizes in orthorhombic space group Cmcm. In complex 1, both L and dca ligands coordinated to Mn(Ⅱ) are in monodentate mode, while in 2, both dca and L ligands act in μ2 bridges to connect Co(Ⅱ) ions. 2 is a 2D coordination layer with two types of cavities, adjacent layers stack each other in a face-to-face fashion to generate a 3D microporous supramolecular architecture with 1D channels along the c-axis, which are occupied by the counterions and solvates.
