A family of planar hexanuclear CoLn clusters with the hydroxyl and nitrogen rich ligand 2-[bis(pyridin-2-ylmethyl) amino]-2-(hydroxymethyl)propane-1,3-diol (HL), formulated as [CoLn(μ-O)(μ-N)(OH)(HO)(HL)]·(CHCO)·20HO [Ln = Dy (1), Gd (2), Tb (3), Eu (4) and Ho (5)], have been synthesized and structurally characterized. They are isomorphous and feature a lucanidae-like arrangement. They are the first examples of 3d-4f clusters with the HL ligand. In addition, the magnetic properties of 1-5 have been investigated and the single-molecule magnet (SMM) behaviour is observed for 1.
合成并表征了一族平面六核钴镧系簇合物，其配体为富含羟基和氮的2-[双(吡啶-2-基甲基)氨基]-2-(羟甲基)丙烷-1,3-二醇(HL)，化学式为[CoLn(μ-O)(μ-N)(OH)(HO)(HL)]·(CHCO)·20HO [Ln = 镝(Dy) (1)、钆(Gd) (2)、铽(Tb) (3)、铕(Eu) (4)和钬(Ho) (5)]。它们是同构的，具有类似lucanidae的排列。它们是以HL为配体的3d-4f簇合物的首例。此外，研究了1-5的磁性，观察到1具有单分子磁体(SMM)行为。
