中文摘要:
      本文合成了一个水合双配体铒配合物,即一水合三异烟酸一(1,10-邻菲咯啉)合铒(Ⅲ),并得到了它的晶体结构。晶体结构数据显示,在配合物中,中心铒(Ⅲ)离子采用八配位扭曲四方反棱柱构型与O6N2组合配位,其中一个氧原子来源于水分子,五个氧原子来源于三个异烟酸分子,而两个氮原子则来自于1,10-邻菲咯啉配体。在晶体结构中,两个O-H···N氢键连同一个C-H···π和一个π···π超分子间作用力一起形成了二维(2D)网状结构,此2D结构进一步通过层间π···π作用力和C-H···O作用力形成3D超分子构型。荧光测试显示,该化合物的荧光光谱大约在370nm-390nm处发射紫色荧光。
英文摘要:
      An erbium(III) complex of Er(ina)3(phen)·H2O [ina = isonicotinic acid, phen = 1,10-phenanthrolin] has been synthesized and characterized. X-ray single crystal diffraction reveals that, in the complex, the central Er(III) ion adopts an eight-coordinated distorted square anti-prism coordination geometry with O6N2 set, where one oxygen atom is from a water molecule and five oxygen atoms come from three ina ligands while two nitrogen atoms are from the phen ligand. In the crystal, two O-H···N hydrogen bonds along with a C-H···π and a π···π supramoleuclar interaction fabricate two-dimensional (2D) networks which further generate a 3D supramolecular architecture via interlayer π···π interactions and extensive C-H···O hydrogen bonds. Fluorescent spectra show that the title complex emits purple fluorescence at about 370 nm and 390 nm.
