Materials Data on MnC5O8 by Materials Project
MnCO4(CO)4 crystallizes in the orthorhombic Pbca space group. The structure is zero-dimensional and consists of thirty-two formaldehyde molecules and eight MnCO4 clusters. In each MnCO4 cluster, Mn2+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Mn–O bond distances ranging from 1.58–1.83 Å. C+2.80+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.31 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn2+ and one C+2.80+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one Mn2+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Mn2+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one Mn2+ atom.
