本文合成了一个水合双配体铒配合物,即一水合三异烟酸-(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1个氧原子来源于水分子,5个氧原子来源于3个异烟酸分子,而2个氮原子则来自于1,10-邻菲咯啉配体。在晶体结构中,2个O—H…N氢键连同1个C—H…π和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。低于1000 nm的荧光测试显示该化合物发射紫色荧光。
In this paper, an erbium complex of hydrated bidentate ligand was synthesized, that is, erbium (III) monoisonicotinate monohydrate (1,10-phenanthroline) and its crystal structure was obtained. The crystal structure data show that in the complex, the central erbium (Ⅲ) ions adopt the octahedrally warped tetragonal anti-prismatic configuration and the O6N2 complex coordinate, in which one oxygen atom is derived from water molecules and five oxygen atoms are from three Isonicotinic acid molecule, while the two nitrogen atoms are derived from 1,10-phenanthroline ligands. In the crystal structure, two O-H ... N hydrogen bonds together with one C-H ... π and π ... π intermolecular forces form a two-dimensional (2D) reticular structure that further passes through the interlayer π ... π force and C-H ... O force form 3D supramolecular configuration. Fluorescence tests below 1000 nm showed that the compound emitted purple fluorescence.
