description: (Fe(CO)4)4(Fe(CO)3)2(Ge)2CO crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two formaldehyde molecules, four germanium molecules, four Fe(CO)3 clusters, and eight Fe(CO)4 clusters. In two of the Fe(CO)3 clusters, Fe3+ is bonded in a 3-coordinate geometry to three C+0.87+ atoms. There is two shorter (1.78 Å) and one longer (1.81 Å) Fe–C bond length. There are three inequivalent C+0.87+ sites. In the first C+0.87+ site, C+0.87+ 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+0.87+ site, C+0.87+ 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 third C+0.87+ site, C+0.87+ is bonded in a distorted linear geometry to one Fe3+ and one O2- atom. The C–O bond length is 1.16 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C+0.87+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+0.87+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one C+0.87+ atom. In two of the Fe(CO)3 clusters, Fe3+ is bonded in a 3-coordinate geometry to three C+0.87+ atoms. There is two shorter (1.78 Å) and one longer (1.80 Å) Fe–C bond length. There are three inequivalent C+0.87+ sites. In the first C+0.87+ site, C+0.87+ 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+0.87+ site, C+0.87+ 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 third C+0.87+ site, C+0.87+ is bonded in a distorted linear geometry to one Fe3+ and one O2- atom. The C–O bond length is 1.16 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C+0.87+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+0.87+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one C+0.87+ atom. In four of the Fe(CO)4 clusters, Fe3+ is bonded in a distorted see-saw-like geometry to four C+0.87+ atoms. There are a spread of Fe–C bond distances ranging from 1.77–1.82 Å. There are four inequivalent C+0.87+ sites. In the first C+0.87+ site, C+0.87+ is bonded in a distorted single-bond geometry to one Fe3+ and one O2- atom. The C–O bond length is 1.16 Å. In the second C+0.87+ site, C+0.87+ 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 third C+0.87+ site, C+0.87+ is bonded in a distorted single-bond geometry to one Fe3+ and one O2- atom. The C–O bond length is 1.16 Å. In the fourth C+0.87+ site, C+0.87+ is bonded in a distorted linear geometry to one Fe3+ and one O2- atom. The C–O bond length is 1.16 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C+0.87+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+0.87+ atom.
