| 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. | |
