The first example of unique coordination induced intramolecular pancake bonding was achieved through the reduction of two bis(pyrazolyl)-tetrazine ligands, affording [MIII2(μ-(bpytz)2)(THMD)4](M = Dy, Y; bpytz = 3,6-bis(3,5-dimethyl-pyrazolyl)-1,2,4,5-tetrazine; TMHD = 2,2,6,6-tetramethyl-3,5-heptanedionate). To provide a cohesive magneto-structural correlation, the mono bis(pyrazolyl)-tetrazine bridged congener [DyIII2(μ-bpytz)(THMD)6]·4(C6H6) was also isolated. Both metal complexes exhibit single-molecule magnet behaviour under an applied dc field.

{Dy2}单分子磁体中前所未有的分子内煎饼结合

通过还原两个双(吡唑基)-四嗪配体,获得[M III 2(μ-(bpytz)2)(THMD)4 ](M = Dy,Y; bpytz = 3,6-双(3,5-二甲基-吡唑基)-1,2,4,5-四嗪; TMHD = 2,2,6,6-四甲基-3,5-庚二酸酯。为了提供内聚的磁结构相关性,还分离了单双(吡唑基)-四嗪桥联同系物[Dy III 2(μ-bpytz)(THMD)6 ]·4(C 6 H 6)。两种金属络合物在施加的直流电场下均表现出单分子磁体行为。
