Two d10 Schiff-base complexes, Zn2(L1)2(H2O)6 ⋅ SO4 (1) and Cd(L2)2(H2O)4 (2) [HL1 = 3-((pyrid-3-yl)-methylene)aminobenzoic acid; HL2 = 4-((pyrid-3-yl)-methylene)aminobenzoic acid], have been synthesized and structurally characterized by elemental analyses, FT-IR spectra, and thermal studies, as well as single crystal X-ray diffraction. Complex 1 is a dinuclear macrocyclic structure with 22-membered
两个 d10 席夫碱配合物,Zn2(L1)2(H2O)6 ⋅ SO4 (1) 和 Cd(L2)2(H2O)4 (2) [HL1 = 3-((pyrid-3-yl)-methylene)氨基苯甲酸;HL2 = 4-((pyrid-3-yl)-methylene)aminobenzoic acid],已通过元素分析、FT-IR 光谱和热研究以及单晶 X 射线衍射进行合成和结构表征。复合物 1 是具有 22 元环的双核大环结构,通过 H 键相互作用组装成 3-D 三明治超分子网络基序;图2是单核结构,通过氢键和π…π堆积接触相互连接,产生另一个3-D超分子网络。此外,还报道了这两种复合物的荧光特性。
