摘要
分别以Cu(ClO4)2·6H2O、Sc(ClO4)3·6H2O和Fe(ClO4)3·9H2O为金属盐,2-硫代巴比妥酸(H3tba)为配体,通过扩散反应得到了3种不同结构的配合物{[Cu6(H2tba)6]·2DMF·xSolvent}(1)、{[Sc(H2tba)3(DMF)]·2DMF}n(2)和[Fe(H2tba)2(H2O)2]n(3),并用红外光谱、元素分析、热重分析和粉末X射线衍射对配合物进行了表征.单晶X射线衍射结构分析表明配合物1是一个具有三方反棱柱构型的六核铜原子簇合物,配合物2是一个具有二维层状结构的化合物,配合物3是一个具有三维网状结构的配位聚合物.配合物1在390 nm光照激发下在735 nm处有强的荧光发射峰.
Abstract
Three complexes with different structures,namely {[Cu6(H2tba)6]·2DMF·xSolvent}(1),{[Sc(H2tba)3(DMF)]·2DMF}n(2),and {[Fe(H2tba)2(H2O)2]·2DMF}n(3)(DMF=N,N-dimethylformamide),were obtained through diffusion reactions using Cu(ClO4)2·6H2O,Sc(ClO4)3·6H2O,and Fe(ClO4)3·9H2O as metal salts,respectively,and 2-thiobarbituric acid(H3tba)as ligand.Complexes 1-3 were further characterized by FTIR,elemental analysis,TGA,and powder X-ray diffraction techniques.Single-crystal X-ray diffraction analysis reveals that complex 1 is a hexa-copper cluster with a trigonal antiprism structure,complex 2 is a 2D sheet structure,and complex 3 is a 3D network structure.Complex 1 exhibited strong luminescent emission spectra at 735 nm with an excitation peak at 390 nm.CCDC:2298695,1;2298696,2;2298697,3.
