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。
The thiocyanate, azido and dicyanamide as bridging ligands were reacted with 2,2’-biimidazole and cadmium nitrate respectively to obtain the ligand [Cd (SCN) 2 (H2biim)] n (1) , 3 compounds were characterized by elemental analysis, IR, TGA and so on. The results showed that there was no significant difference between the two compounds (Cd2 (NO3) (dca) 3 (H2biim) Their crystal structure. The results show that compounds 1 and 2 are one-dimensional chain structures connected by μ1,3-SCN- and μ1,1-N3-double bridge, respectively. Compound 3 is based on μ1,5-dca- and μ3,3’-H2biim Cross-bridged two-dimensional network structure. Their fluorescence properties were also initially analyzed.
