Materials Data on Os2C3 by Materials Project

Abstract

Os2C3 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. there are three inequivalent Os2- sites. In the first Os2- site, Os2- is bonded in a 7-coordinate geometry to seven C+1.33+ atoms. There are a spread of Os–C bond distances ranging from 2.07–2.37 Å. In the second Os2- site, Os2- is bonded to six C+1.33+ atoms to form distorted edge-sharing OsC6 octahedra. There are a spread of Os–C bond distances ranging from 2.08–2.15 Å. In the third Os2- site, Os2- is bonded in a 6-coordinate geometry to six C+1.33+ atoms. There are a spread of Os–C bond distances ranging from 2.12–2.18 Å. There are three inequivalent C+1.33+ sites. In the first C+1.33+ site, C+1.33+ is bonded in a 4-coordinate geometry to four Os2- atoms. In the second C+1.33+ site, C+1.33+ is bonded in a distorted pentagonal planar geometry to five Os2- atoms. In the third C+1.33+ site, C+1.33+ is bonded in a 4-coordinate geometry to four Os2- atoms.
