Metal-Organic Complexes Based on 3,6-Bis(N-imidazolyl/benzimidazolyl) Pyridazine:Syntheses, Structures, Emission and Photocatalytic Properties

用溶剂热法设计、合成了4个金属-有机配合物[Mn(L^1)_4(OH)_2](1),{[MnL^1(H_2O)_4]SO_4}_n(2),[CdL^2(NO_3)_2]_n(3)和{[Co(L^2)_2](PF_6)_2}_n(4),(L^1=3,6-二(N-咪唑基)哒嗪,L^2=3,6-二(N-苯并咪唑基)哒嗪),并通过元素分析、红外、X射线单晶衍射对配合物结构进行了表征,测试结果表明配合物1具有单核结构,2为一维链结构,配合物3和4均为二维网状结构。此外,对配合物3和4的固态荧光性能及光催化的性能做了进一步研究。

Four new metal-organic coordination polymers namely, [Mn（L^1）4（OH）2] （1）, {[MnL^1（H2O）4] （SO4）}n （2）, [CdL^2（NO3）2]n （3）, {[Co（L^2）2]（PF6）2}n （4） （L^1=3,6-bis（N-imidazolyl） pyridazine, L^2=3,6-bis（N-benzimidazolyl） pyridazine] have been synthesized under solvothermal conditions and characterized by elemental analyses, IR spectra as well as single-crystal X-ray diffraction analysis. The analysis reveals that complex 1 has a mononuclear structure, and complex 2 features a 1D structure. Complexes 3 and 4 exhibit 2D network structures. The fluorescence and photocatalytic activities of the complexes 3 and 4 have been investigated and discussed. CCDC： 1444988, 1, 1444989, 2; 1022876, 3; 1022877, 4.
