A triferrocenyl trithiophosphite was studied by X-ray single-crystal diffraction. Triferrocenyl trithiophosphite has nine axes of internal rotation: three P-S bonds, three C-S bonds and three Fe-cyclopentadienyl axes. Rotation around the P-S bonds results in a totally asymmetric structure with three ferrocenylthio groups exhibiting different orientations towards the phosphorus lone electron pair (LEP). A comparison of DFT calculations and X-ray diffraction data is presented, herein we show which conformations are preferred for a given ligand.
通过X射线单晶衍射对三茂铁基亚硫代磷酸酯进行了研究。三茂铁基亚硫代磷酸酯有九个内旋转轴：三个P-S键、三个C-S键和三个Fe-环戊二烯基轴。围绕P-S键的旋转导致完全不对称的结构，三个二茂铁硫基对磷孤电子对（LEP）呈现不同的取向。给出了DFT计算和X射线衍射数据的比较，在此我们展示了给定配体的哪些构象是优选的。
