合成了氰根桥联配合物[(Ni(2’2-bipy)2)3(Fe(CN)6)2].13H2O,使用元素分析、红外光谱等对配合物进行了表征。红外光谱显示金属离子通过氰根桥联传递磁相互作用,是属于桥式氰根配体的CN伸缩振动。对该配合物的磁化率测定表明金属离子通过氰根传递磁作用,求得分子磁体有效磁距μeff。并根据Curie-Weiss定律拟合获得居里常数C=6.83cm3.kmol-1和顺磁居里温度θ=9.39K。
The cyanide bridged complex [(Ni (2’2-bipy) 2) 3 (Fe (CN) 6) 2] .13H2O was synthesized and characterized by elemental analysis and IR spectroscopy. Infrared spectroscopy shows that metal ions transfer magnetic interactions through cyanide bridges, which are CN stretching vibration belonging to bridged cyanide ligands. The determination of the magnetic susceptibility of the complex shows that metal ions transfer the magnetism through the cyanide to obtain the effective magnetic moment μeff of the molecular magnet. The Curie’s constant C = 6.83cm3.kmol-1 and the paramagnetic Curie temperature θ = 9.39K were fitted according to the Curie-Weiss law.
