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

利用金属络合物第一配位球中的氟特定相互作用，实验上实现了模型体系的不同自旋态。具有不同取代方式的二茂铁(含氧化态+IV的铁)将与氟化物和氟基配体(如F−、[BF4]−、[SbF6]−、[NiF6]2−、XeF2)结合。SQUID磁测量和Möber Bauer谱将被用来确定所需的产物是否存在于S=0或S=1的自旋态。

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.
