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(英文)

Hydrothermal Syntheses,Crystal Structures and Luminescent Properties of Binuclear Zn(Ⅱ) and Co(Ⅱ) Complexes Assembled by 4-Carboxymethoxy Phenylacetic Acid

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。

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 of complex 1 has also been investigated,and the result reveals that it displays luminescent property in the voilet region.
