两种新的铜(Ⅱ)混配体绿色晶体的合成与表征
Synthesis and Characterization of Two New Copper(Ⅱ) Mixed-ligand Green Crystals
【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(H3ntb)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{[Cu3(ntb)2(bpep)(H2O)2](H2O)4}n(1)和[Cu2(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。
【Abstract】 Two novel Cu( Ⅱ)-organic coordination polymers,{ [Cu3( ntb)2( bpep)( H2O)2]( H2O)4}n( 1) and[Cu2( Hntb)2( bpeb) ]n( 2),were synthesized by cupric( Ⅱ) nitrate,4,4’,4’’-nitrilotribenzoic( H3ntb) 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.
