Materials Data on Fe2C9(O4F)2 by Materials Project
(Fe(CO)3)2(CO)2CF2 crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of two difluoromethane molecules, four formaldehyde molecules, and four Fe(CO)3 clusters. In two of the Fe(CO)3 clusters, Fe3+ is bonded in a 3-coordinate geometry to three C+1.33+ atoms. There is two shorter (1.80 Å) and one 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 1.16 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 1.16 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 two of the Fe(CO)3 clusters, Fe3+ is bonded in a 3-coordinate geometry to three C+1.33+ atoms. There is two shorter (1.80 Å) and one longer (1.82 Å) Fe–C bond length.

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 1.16 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.
