4-氧乙酸苯乙酸构筑的双核Zn(Ⅱ)和Co(Ⅱ)配合物的合成,晶体结构及荧光性能

摘要

Two new binuclear complexes, [M2L2(phen)2(H2O)2] (M=Zn, 1; Co, 2), assembled by 4-carboxymethoxy phenylacetic acid (H2L) and 1,10-phenanthroline (phen), have been synthesized under hydrothermal conditions.Single-crystal X-ray diffraction reveals complex 1 and 2 are isostructural, crystallized in monoclinic system, P21/c space group. The metal ion center is six-coordinated in a distorted octahedral geometry. Two neighboring center metal ions are linked together by two bridging L ligands forming a binuclear cage second building units (SBUs),and the SBUs are further linked to form 1D chain through intermolecular hydrogen bonds. In addition, π-π stacking interactions between the phen rings of the adjacent chains result in a 2D layer. The luminescence ofcomplex 1 has also been investigated, and the result reveals that it displays luminescent property in the voilet region.%用水热法合成得到2个新配合物,[M2L2(phen)2(H2O)2](L=4-氧乙酸苯乙酸,phen=1,10-邻菲咯啉,M=Zn,1;Co,2),并测定了它们的晶体结构.配合物1和2为异质同晶,单斜晶系,P21/c空间群.中心金属M为六配位,相邻的M(Ⅱ)通过2个桥连的配体形成双核笼状次级结构单元,通过氢键和π-π堆积弱作用链接形成二维层结构.通过对配合物1的固态荧光测试,结果表明其在紫光区显示发光效应.
