Materials Data on FeSi2C4(Cl3O2)2 by Materials Project
Fe(CO)4(SiCl3)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four trichlorosilane molecules and two Fe(CO)4 clusters. In each Fe(CO)4 cluster, Fe3+ is bonded in a square co-planar geometry to four C+0.75+ atoms. There is two shorter (1.82 Å) and two longer (1.83 Å) Fe–C bond length. There are two inequivalent C+0.75+ sites. In the first C+0.75+ site, C+0.75+ is bonded in a distorted single-bond geometry to one Fe3+ and one O2- atom. The C–O bond length is 1.15 Å. In the second C+0.75+ site, C+0.75+ is bonded in a distorted linear geometry to one Fe3+ and one O2- atom. The C–O bond length is 1.15 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C+0.75+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+0.75+ atom.
