| 摘要: 以硫氰酸根、叠氮基、二氰胺为桥联配体，分别与2，2′-联咪唑和硝酸镉反应，获得配聚物[Cd(SCN)2(H2biim)]n (1), [Cd(N3)2(H2biim)]n (2)和[Cd2(NO3)(dca)3(H2biim)2.5]n (3)，3个化合物通过元素分析、IR、TGA等表征，并测定了它们的晶体结构。结果表明：化合物1和2分别是以μ1,3-SCN-和μ1,1-N3-双桥连接的一维链状结构，化合物3是以μ1,5-dca-和μ3,3′-H2biim交叉桥连的二维网状结构。对它们的荧光性质也进行了初步分析。 | |

| Abstract: Three polymeric compounds [Cd(SCN)2(H2biim)]n (1), [Cd(N3)2(H2biim)]n (2) and [Cd2(NO3)(dca)3(H2biim)2.5]n (3)(H2biim=2,2′-H2biimidazole, dca=dicyanamide), have been synthesized and characterized. Compound 1 forms a 1D chain where [CdS2N4] octahedra are doubly bridged by two μ1,3-SCN- ligands. These chains are stacked together through hydrogen bonds and π-π interactions forming a 2D supermolecular network. In compound 2, the [CdN6] octahedra are doubly bridged by two μ1,1-N3- bridges to form a chain. These chains are stacked together through hydrogen bonding interactions forming a 3D supermolecular structure. In compound 3, the Cd2 ions are alternately bridged by two μ1,5-dca- and one μ3,3′-H2biim bridge along b-axis and form a chain. These chains are bridged by μ1,5-dca- to form a plane. Cd1 and Cd2 atoms are bridged by one dca- with Cd1 locate at either side of the plane. The luminescent properties of these compounds were studied. CCDC: 657894, 1; 657895, 2; 657896, 3. | |
