Materials Data on Fe2C9O7F4 by Materials Project

(Fe(CO)3)2CO(CF2)2 crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of eight difluoromethane molecules, four formaldehyde molecules, and eight Fe(CO)3 clusters. In four of the Fe(CO)3 clusters, Fe3+ is bonded in a 3-coordinate geometry to three C+1.33+ atoms. There is one shorter (1.80 Å) and two longer (1.82 Å) Fe–C bond length. There are two inequivalent C+1.33+ sites. In the first C+1.33+ site, C+1.33+ 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+1.33+ site, C+1.33+ is bonded in a distorted single-bond 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+1.33+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+1.33+ atom. In four of the Fe(CO)3 clusters, Fe3+ is bonded in a 3-coordinate geometry to three C+1.33+ atoms. There is one shorter (1.80 Å) and two longer (1.82 Å) Fe–C bond length. There are two inequivalent C+1.33+ sites. In the first C+1.33+ site, C+1.33+ is bonded in a distorted linear geometry to one Fe3+ and one O2- atom. The C–O bond length is 1.15 Å. In the second C+1.33+ site, C+1.33+ is bonded in a distorted single-bond 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+1.33+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+1.33+ atom.
