我们报告了一个罕见的混合价铁化合物与FeNNFe核心,这使得洞察到单电子还原和氧化的结构,光谱和磁性的影响的例子。在新的化合物中,奇数电子是本地化的判断,从穆斯堡尔谱在80 K和红外光谱在室温下,和到N2单元的背键之间的二铁(I)和二铁(0)同系物。磁化率和弛豫研究系列的FeNNFe化合物显示出显着的磁各向异性,但通过势垒的途径,使相当快的磁弛豫。通过红外光谱和穆斯堡尔谱研究发现,一种新的混合价态铁氮配合物具有定价态结构和缓慢的磁弛豫。
We report a rare example of a mixed-valence iron compound with an FeNNFe core, which gives insight into the structural, spectroscopic, and magnetic influences of single-electron reductions and oxidations. In the new compound, the odd electron is localized as judged from Mössbauer spectra at 80 K and infrared spectra at room temperature, and the backbonding into the N2 unit is intermediate between diiron(I) and diiron(0) congeners. Magnetic susceptibility and relaxation studies on the series of FeNNFe compounds show significant magnetic anisotropy, but through-barrier pathways enable fairly rapid magnetic relaxation. A new mixed-valence iron-dinitrogen complex has localized valence by IR and Mossbauer spectroscopies, and slow magnetic relaxation.
