新型配合物Mn(4,4′-bpy)(tca)2的合成、结构及磁性质研究

摘要

A new complex[Mn(4,4'-bpy)(tca)2] (4,4'-bpy=4,4'-bipyridine,tca=tratts-cinnamic acid) had been synthesized under hydrothermal conditions.The structure of the complex was characterized by elemental a-nalysis,infrared spectrum,and X-ray single crystal diffraction.The structure analysis indicated that the target complex showed an isomorphism,Trignnal,P-3 space group.Eventually,it formed a novel three-dimensional structure and the main crystal parameters were as follows:a = 3.1755(3) nm,b=3.1755(3) nm,c = 1.26751 (15) nm,a=90.00°,β=90.00°,γ=120.00°,V=11.069(2).nm3,Z=2.The target complex had antiferromagnet-ic interaction.%在水热条件下合成了新型配合物[Mn(4,4′-bpy) (tca)2](4,4′-bpy=4,4′-bipyridine,tca=trans-cinnamic acid),通过元素分析、红外光谱和X-射线单晶衍射分析对配合物进行了结构表征.结果表明,目标配合物是Trignnal晶系,P-3空间群,具有新颖的三维结构,主要晶体学参数为:a=3.1755(3) nm,b=3.1755(3) nm,c=1.26751(15) nm,α=90.00°,β=90.00°,γ=120.00°,V=11.069(2) nm3,Z=2.目标配合物具有反铁磁相互作用的磁性质.
