Abstract

A one-pot synthetic procedure yields the octanuclear Fe(III) complexes Fe(8)(micro(4-)O)(4)(micro-pz())(12)X(40, where X = Cl and pz() = pyrazolate anion (pz = C(3)H(3)N(2)-) (1), 4-Cl-pz (2), and 4-Me-pz (3) or X = Br and pz() = pz (4). The crystal structures of complexes 1-4, determined by X-ray diffraction, show an Fe(4)O(4)-cubane core encapsulated in a shell composed of four interwoven Fe(micro-pz())(3)X units. Complexes 1-4 have been characterized by 1H NMR, infrared, and Raman spectroscopies. Mössbauer spectroscopic analysis distinguishes the cubane and outer Fe(III) centers by their different isomer shift and quadrupole splitting values. Electrochemical analyses by cyclic voltammetry show four consecutive, closely spaced, reversible reduction processes for each of the four complexes. Magnetic susceptibility studies, corroborated by density functional theory calculations, reveal weak antiferromagnetic coupling among the four cubane Fe centers and strong antiferromagnetic coupling between cubane and outer Fe atoms of 1. The structural similarity between the antiferromagnetic Fe(8)(micro(4-)O)(4) core of 1-4 and the antiferromagnetic units contained in the minerals ferrihydrite and maghemite is demonstrated by X-ray and Mössbauer data.

摘要

一锅法合成步骤得到了八核铁（III）配合物Fe(8)(μ4 - O)(4)(μ - pz*)(12)X4，其中X = Cl且pz* = 吡唑阴离子（pz = C3H3N2 - ）（1）、4 - Cl - pz（2）和4 - Me - pz（3），或者X = Br且pz* = pz（4）。通过X射线衍射确定的配合物1 - 4的晶体结构显示，一个Fe(4)O(4) - 立方烷核心被包裹在由四个相互交织的Fe(μ - pz*)(3)X单元组成的壳层中。配合物1 - 4已通过1H NMR、红外和拉曼光谱进行了表征。穆斯堡尔光谱分析通过其不同的同质异能位移和四极分裂值区分了立方烷和外部的铁（III）中心。循环伏安法的电化学分析表明，这四种配合物中的每一种都有四个连续的、间隔紧密的可逆还原过程。磁性研究得到密度泛函理论计算的证实，揭示了四个立方烷铁中心之间的弱反铁磁耦合以及配合物1的立方烷和外部铁原子之间的强反铁磁耦合。X射线和穆斯堡尔数据表明了配合物1 - 4的反铁磁Fe(8)(μ4 - O)(4)核心与矿物水铁矿和磁赤铁矿中所含反铁磁单元之间的结构相似性。
