A new family of dinuclear iron(II) spin‐crossover (SCO) compounds with the formula [Fe2(μ‐L)2]X4, with three different counteranions [X = BF4– (1), ClO4– (2) and F3CSO3– (3)], was prepared and characterized by single‐crystal X‐ray diffraction, variable‐temperature magnetic susceptibility and Mössbauer measurements. These are the first dinuclear iron(II) SCO complexes with a 1,3,4‐thiadiazole bridging
分子式为[Fe 2(μL)2 ] X 4的双核铁(II)自旋交联(SCO)化合物的新家族,带有三种不同的抗衡离子[X = BF 4 –(1),ClO 4 –(2)和F 3 CSO 3 –(3)],并通过单晶X射线衍射,可变温度磁化率和Mössbauer测量进行了表征。这些是第一个具有1,3,4-噻二唑桥联配体L的双核铁(II)SCO配合物L = 2,5-双[(2-吡啶基甲基)氨基]甲基-1,3,4-噻二唑} 。磁性测量结果表明,从抗磁[LS–LS]状态开始,室温下三种化合物的SCO逐渐且不完全。反磁性基态与单晶X射线衍射和Mössbauer数据一致。
