一维链{Mn_2(2,2'-bipy)_4(3,3'-tda)·2ClO_4)_n配合物的合成、结构与磁性研究

摘要

@@ 由于柔性羧酸配体具有丰富多样的配位方式和灵活多变的分子结构,可以用来设计合成多种具有新颖结构和性质的配位聚合物,因而正逐渐引起研究者的关注[1-6].%By using 3,3'-thiodipropionic acid (3,3'-tdaH_2) as typical ligand and 2,2' -bipyridine (2,2'-bipy) as supporting ligand, a 1D complex {[Mn_2(2,2'-bipy)4(3,3'-tda)]·2ClO_4}_n (1) was synthesized and characterized by X-ray diffraction single crystal structure analysis, elemental analysis and IR spectra. Variable-temperature magnetic susceptibility was measured in the range 2 ～300 K. Research of magnetism shows weak antiferromagnetic interaction between the adjacent manganese(Ⅱ) ions in the complex.
