【摘要】 <正>稀土离子具有独特的电子结构和成键特征,配位数高且多变,因而稀土配合物能表现出独特的光、电、磁性质。目前,设计和合成含有稀土离子的超分子配合物,作为发光分子器件和荧光探针是稀土配位化学、超分子化学等研究领域的热点课题之一。酰胺型多足配体在与金属离子配位时,更多还原

【Abstract】 Solid complexes of rare earth nitrate with a new amide type tripodal ligand, 2,2’,2"-nitrilotris-（N-phenylacetamide）（L）has been prepared and characterized by elemental analysis,IR spectra and molar conductivity measurements.The X-ray single-crystal diffraction analysis indicates that the complex [EuL₂（C₃H₆O）]·（NO₃）₃（H₂O）₅（HCCl₃）₂ conformed to a 1:2 metal-to-ligand stoichiometry, which is very rare in the rare earth nitrate complexes with such ligand.The coordination polyhedron around Tb is a distorted tricapped trigonal prism.Furthermore,the ML₂ complex units are hydrogen bonded to yield infinite 3D supramolecular network.At room temperature,the Tb complex solid exhibited characteristic emission under UV light excitation.更多还原
