Abstract:基于不同位阻的三氰基构筑单元和双齿配体,合成了2个氰基桥联的Fe(Ⅲ)-Mn(Ⅱ)链状化合物.利用不同的结构扭曲类型调控了它们的磁性相互作用.化合物{ [Fe(Ⅲ)(PzTp)(C N)3][Mn(Ⅱ)(5,5'-dmbpy)2]ClO4}n (1;PzTp=tetrakis(pyrazolyl)borate;5,5'-dmbpy=5,5'-dimethyl-2,2'-bipyridine)显示为左右手螺旋链的一维2,2-CC链状结构并且表现出亚铁磁行为.化合物{[Fe(Ⅲ) (Tp*)(CN)3]2[Mn(Ⅱ)(dpqc)]·CH3OH·H2O}n(2;Tp*=hydridotris(3,5-dimethylpyrazolyl)borate;dpqc=dipyrido[3,2-a:2',3'-c]-(6,7,8,9-tetrahydro)phenazine)具有一维4,2-带状的双链结构并且表现出典型的反铁磁性相互作用.
