Materials Data on Os2C3 by Materials Project
Os2C3 crystallizes in the tetragonal P-4c2 space group. The structure is three-dimensional. there are three inequivalent Os2- sites. In the first Os2- site, Os2- is bonded in a 6-coordinate geometry to six C+1.33+ atoms. There are two shorter (2.03 Å) and four longer (2.19 Å) Os–C bond lengths. In the second Os2- site, Os2- is bonded in a 8-coordinate geometry to eight C+1.33+ atoms. There are four shorter (2.16 Å) and four longer (2.31 Å) Os–C bond lengths. In the third Os2- site, Os2- is bonded in a distorted octahedral geometry to six C+1.33+ atoms. There are four shorter (2.07 Å) and two longer (2.36 Å) Os–C bond lengths. There are two 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.
