摘要

在 Cu2+/4f 化学中结合使用 2-(2-吡啶基)-1,3-丙二醇（pypdH2）和 2-羟甲基-2-(2-吡啶基)-1,3-丙二醇（pyptH3），产生了一系列新的等结构[Cu6M4(pypt)4(pypdH)4(NO3)8] [M = Gd (1)、Tb (2)、Dy (3) 和 Y (4)]配合物。这些化合物基于前所未有的三层对称 [Cu6M4(μ-ΟR)16]8+结构核心，由有机配体的烷氧基桥臂连接金属离子而形成。对复合物 1 - 3 进行的直流磁感应强度研究表明，铁磁交换相互作用占主导地位，表明存在较大的自旋基态值。交流磁研究表明，1-3 复合物中存在慢磁弛豫。

A New Family of Heterometallic [Cu6M4] (M = Gd, Tb, Dy and Y) Clusters Derived from the Combined use of Selected Pyridyl Poly-alcohol Ligands

The combined use of 2-(2-pyridyl)-1,3-propane-diol (pypdH2) and 2-hydroxymethyl-2-(2-pyridyl)-1,3-propane-diol (pyptH3) in Cu2+/4f chemistry has afforded a new family of isostructural [Cu6M4(pypt)4(pypdH)4(NO3)8] [M = Gd (1), Tb (2), Dy (3), and Y (4)] complexes. These compounds are based on an unprecedented three-layered symmetric [Cu6M4(μ-ΟR)16]8+ structural core, formed from the connection of the metal ions by bridging alkoxide arms of the organic ligands. Direct current magnetic susceptibility studies for complexes 1 - 3 revealed the presence of dominant ferromagnetic exchange interactions, suggesting the existence of large spin ground state values. Alternating current magnetic studies indicate the presence of slow-magnetic relaxation in 1 - 3.
