Spin State Control of Organometallic Fe(IV) Compounds through Interactions with Fluoride and Fluoride-Containing Ligands (B07#)

在金属配合物的第一配位球中的氟特异性相互作用将用于实验实现模型系统的不同自旋状态。具有不同取代模式的二茂铁二价阳离子（含有氧化态+IV的铁）将与氟化物和氟基配体（例如F−、[BF 4]−、[SbF 6]−、[NiF 6]2−、XeF 2）结合。SQUID-磁强计和穆斯堡尔谱将用于确定所需的产品是否存在于S = 0或S = 1的自旋状态。

Fluorine-Specific interactions in the first coordination sphere of metal complexes shall be used to experimentally realize different spin states of a model system. Ferrocene-dications (containing iron in oxidation state +IV) with varying substitution patterns will be combined with fluoride and fluorine-based ligands (e.g. F−, [BF4]−, [SbF6]−, [NiF6]2−, XeF2). SQUID-magnetometry and Mößbauer-spectroscopy will be used to determine whether the desired products exist in S = 0 or S = 1 spin state.
