摘　　要：溶剂热条件下,通过控制溶剂比例,用硝酸铜、4,4’,4’’-三羧酸三苯胺(H_3ntb)和1,4-bis[2-(4-pyridyl)ethenyl]benzene(bpeb)合成了两种新颖的铜-有机配位聚合物{[Cu_3(ntb)_2(bpep)(H_2O)_2](H_2O)_4}_n(1)和[Cu_2(Hntb)_2(bpeb)](2)。单晶X-射线衍射研究表明,化合物1是一个(3,4,4)连接的三维配位聚合物。化合物2是一个含螺旋结构的三维配位聚合物。结晶样品通过元素分析、红外光谱(IR)、热重(TG)和粉末X射线衍射等进行了表征。在365 nm波长光照射下,晶体1和2分别显墨绿色和亮绿色.两种新物质都具有良好的热稳定性,可以作为金属配合物颜料。Two novel Cu(Ⅱ)-organic coordination polymers,{[Cu 3(ntb)2(bpep)(H 2 O)2](H 2 O)4}n(1)and[Cu 2(Hntb)2(bpeb)]n(2),were synthesized by cupric(Ⅱ)nitrate,4,4,4-nitrilotribenzoic(H 3 ntb)and 1,4-bis[2-(4-pyridyl)ethenyl]benzene(bpeb)via solvent-ratio control under solvothermal conditions.Single-crystal structural analysis revealed that compound 1 was a(3,4,4)-connected three-dimensional coordination network,and compound 2 was three-dimensional coordination polymer with helical structures.The elemental analysis,thermal stability,powder X-ray diffractions of two crystals were carried out.Under 365 nm ultraviolet light,crystals 1 and 2 showed dark green and bright green respectively.Two compounds had good thermal stability,can be used as metal-complex dyes.
