以3，5-二甲(丙)基-4-氨基-1，2，4-三唑为配体，与CuI在H₂O/MeCN混合溶剂热合成了2个构型不同的Cu₄I₄超分子化合物{Cu₂(aadmtrz) I₂]·CH₃CN}_n(1)和Cu₂(dptrz) I]_n(2)(aadmtrz=4-((1-氨乙基)-氨基)-3，5-二甲基-1，2，4-三唑，dptrz=3，5-二丙基-1，2，4-三唑)，并进行了元素分析，红外，X射线粉末衍射及单晶衍射等表征。2个配合物中Cu₄I₄构型不同，配合物1中，Cu₄I₄簇连结成一个8环椅式-椅式结构，通过配体连接成(4，4)二维菱形格子结构；而配合物2中，Cu₄I₄簇呈畸变的立方烷结构，构成了含有19.5%孔隙率三维孔洞聚合物，其结构可简化为(3，4)-连接的拓朴结构。同时，在常温下研究了2个配合物的固体荧光性质。

Syntheses,Crystal Structures and Luminescence Properties of Two Cu4I4 Coordination Polymers Based on 3,5-Dialkyl-1,2,4-triazole

Two Cu₄I₄ coordination polymers,{Cu₂(aadmtrz) I₂]·CH₃CN}_n(1) andCu₂(dptrz) I]_n(2)(aadmtrz=4-((1-aminoethylidene)-amino)-3,5-dimethyl-1,2,4-triazole,dptrz=3,5-dipropyl-1,2,4-triazole),have been synthesized by the solvothermal reactions of CuI and 3,5-dialkyl-4-amino-1,2,4-triazole ligands in mixed H₂O/MeCN solution and characterized using elemental analysis,IR,PXRD and single-crystal X-ray diffraction.The structures of the Cu₄I₄ units in the polymers are different.The Cu₄I₄ cluster in complex 1 is an inorganic 8-membered ring with a chair-chair conformation,while the one in complex 2 is a distorted cube.Complex 1 exhibits 2D 4,4-connected rhombic-grid.Complex 2 is a (3,4)-connected framework with 19.5% porosity.In addition,the luminescent properties of the complexes in the solid state were also investigated.CCDC:1437794,1;1437795,2.
