Diamagnetic -dicyanidoferrate(II) complexes bearing blocking aromatic diimines, -[Fe(CN)(L)] (L = 2,2'-bipyridine, 1,10'-phenanthroline) serve as metalloligands to Dy centres leading to a rigid cyanido-bridged chain of vertex-sharing {DyFe} squares which constrains the equatorial plane of embedded 4f metal ions. This results in a novel convenient route to rationally designed single-molecule magnets as the magnetic anisotropy of Dy centres can be efficiently generated by inserting aromatic -oxide ligands on labile axial positions.
带有位阻芳香二亚胺的抗磁性二氰基铁（II）配合物，-[Fe(CN)(L)]（L = 2,2'-联吡啶，1,10'-菲咯啉）作为金属配体与镝中心结合，形成由顶点共享的{DyFe}正方形组成的刚性氰基桥连链，该链限制了嵌入的4f金属离子的赤道平面。这为合理设计单分子磁体提供了一条新的便捷途径，因为通过在不稳定的轴向位置插入芳香族氧化物配体，可以有效地产生镝中心的磁各向异性。
