3-羧基-1,2,4-三氮唑MnⅡ配合物的合成、结构及荧光性质
Synthesis, Structure and Fluorescence Properties of Manganese(Ⅱ) Complex Based on 3-Carboxvl-1,2,4-triazole
摘要
Abstract
In order to investigate the properties of 3-carboxyl-1,2,4-triazole complexes,a novel complex,[Mn(C3H2N3O2)2 (H2O) 2],was synthesized by the hydrothermal method.The properties of the complex were characterized by Fourier transform infrared spectroscopy (IR),element analysis,thermal gravimetric anlysis(TGA) and powder X-ray diffraction (PXRD).The single crystal X-ray analysis reveals that the complex is a unique single-core structure and belongs to the monoclinic crystal system in space group P21/c.The coordination number of Mn Ⅱ is six.The Mn Ⅱ atom is located on an inversion centre.Each Mn Ⅱ atom is coordinated by two O atoms and two N atoms from two 3-carboxyl-1,2,4-triazole anions and two coordinated water molecules to form a slightly distorted octahedral geometry.The discrete molecules of the complex are furthermore linked,resulting in a three-dimensional network structure through extensive intermolecular hydrogen bonds and πr-tr interactions.Solid fluorescence of the complex shows an emission peak at 517 nm.Compared with the ligand,there is a 7 nm blue shift.The research provides a reference for exploiting new metal-organic complex fluorescent materials.关键词
