合成了两个苯氧基和氰基桥联的一维配合物NiII2GdIII2FeIII3(1)和NiII2DyIII2FeIII3(2)。它们是第一个五氰基铁氧体桥联的异三金属络合物。磁性研究表明,化合物1和2均存在铁磁相互作用,化合物2表现为单分子磁体(SMM)行为,势垒为14.8K。
Two phenoxo- and cyanido-bridged one-dimensional complexes NiII2GdIII2FeIII3 (1) and NiII2DyIII2FeIII3 (2) have been prepared. They are the first pentacyanidoferrite-bridged heterotrimetallic complexes. Magnetic studies reveal that overall ferromagnetic interactions are present in complexes 1 and 2, and complex 2 shows single-molecule magnet (SMM) behaviour with an energy barrier of 14.8 K.
