Materials Data on CsMnCl3O2 by Materials Project
CsMnO2Cl3 crystallizes in the orthorhombic Pcca space group. The structure is three-dimensional. Cs is bonded to four equivalent O and eight Cl atoms to form a mixture of distorted corner, edge, and face-sharing CsCl8O4 cuboctahedra. There are two shorter (3.43 Å) and two longer (3.52 Å) Cs–O bond lengths. There are a spread of Cs–Cl bond distances ranging from 3.65–3.84 Å. Mn is bonded in a 6-coordinate geometry to two equivalent O and four Cl atoms. Both Mn–O bond lengths are 2.05 Å. There are two shorter (2.29 Å) and two longer (2.62 Å) Mn–Cl bond lengths. O is bonded in a 1-coordinate geometry to two equivalent Cs, one Mn, and one O atom. The O–O bond length is 1.31 Å. There are two inequivalent Cl sites. In the first Cl site, Cl is bonded in a distorted bent 120 degrees geometry to two equivalent Cs and two equivalent Mn atoms. In the second Cl site, Cl is bonded in a distorted single-bond geometry to three equivalent Cs and one Mn atom.
