Dissolution of FeBr in a mixture of acetonitrile and 3,4-lutidine in the presence of an amine results in the formation of an [Fe] molecular metal oxide containing alternating layers of tetrahedral and octahedral Fe ions. Mass spectrometry suggests the cluster is formed quickly and remains stable in solution, while magnetic measurements and DFT calculations reveal competing antiferromagnetic exchange interactions.
在胺存在的情况下，将溴化铁溶解于乙腈和3,4-二甲基吡啶的混合物中，会形成一种含有四面体和八面体铁离子交替层的[Fe]分子金属氧化物。质谱分析表明该簇合物形成迅速且在溶液中保持稳定，而磁性测量和密度泛函理论计算揭示了相互竞争的反铁磁交换相互作用。
