摘 要:在中温混合溶剂热条件下合成了两个金属铜配位聚合物Cu3(2,2′-bipy)2(C8H4O4)2(C8H5O4)2和Cu(Ⅰ)Cu(Ⅱ)(4,4′-bipy)1.5(C8H4O4)(C8H5O4)(bipy=联吡啶,C8H4O4=1,3-间苯二甲酸),并对其进行了单晶结构解析及相关性能表征.配合物Cu3(2,2′-bipy)2(C8H4O4)2(C8H5O4)2(1)晶体属三斜晶系,P1空间群,a=1.03314(4)nm,b=1.08350(3)nm,c=1.15826(4)nm,α=83.104(2)°,β=84.609(2)°,γ=66.125(2)°,Z=1.配合物Cu(Ⅰ)Cu(Ⅱ)(4,4′-bipy)1.5(C8H4O4)(C8H5O4)(2)晶体属三斜晶系,P1空间群,a=1.06979(3)nm,b=1.09209(3)nm,c=1.47887(3)nm,α=91.795(2)°,β=93.2460(10)°,γ=118.6170(10)°,Z=2.通过使用不同的有机碱配体(2,2′-联吡啶和4,4′-联吡啶),并调节不同有机碱配体的用量,得到了结构不同的两个目标晶体产物相.产物均可稳定到300℃.Two copper coordination polymers,Cu3(2,2'-bipy)2(C8n4O4)2(C8H5O4)2andCu(Ⅰ)Cu(Ⅱ)(4,4'-bipy)1.5(,C8H4O4)(C8H5O4)were hydrothermally synthesized in mixed solvothermal and characterized by single crystal X-ray diffraction.Cu3(2,2'-bipy)2(C8n4O4)2(C8H5O4)2( 1 ) crystallizes in a triclinic system with space group P1-and cell parameters,a=1.03314(4) nm, b =1.08350(3) nm, c= 1.15826(4) nm, α=83.104(2)°,β=84.609(2)°,γ=66.125(2)°, and Z=1.Cu(Ⅰ)Cu(Ⅱ)(4,4'-bipy)1.5(C8n4O4)2(C8H5O4)2(2) crystallizes also in a triclinic system with space group P1-and cell parameters, a = 1. 06979(3) nm, b = 1. 09209(3) nm, c = 1. 47887(3) nm, α=91.795(2)°β=93.2460(10)°,y=118.6170(10)°, and Z = 2. Their syntheses were performed under the similar conditions from different organic alkali ligands 2,2'-bipy and 4,4'-bipy at different concentrations. These changes gave rise to the corresponding change in final crystal structure of products. Both compounds are thermally stable up to 300 ℃.
