Materials Data on Sb2OsC6(OF2)6 by Materials Project

Abstract

Os(CO)6(SbF6)2 is Fluorite structured and crystallizes in the tetragonal P4/mnc space group. The structure is zero-dimensional and consists of two Os(CO)6 clusters and four SbF6 clusters. In each Os(CO)6 cluster, Os2- is bonded in an octahedral geometry to six C4+ atoms. There are two shorter (2.01 Å) and four longer (2.02 Å) Os–C bond lengths. There are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a distorted single-bond geometry to one Os2- and one O2- atom. The C–O bond length is 1.14 Å. In the second C4+ site, C4+ is bonded in a distorted linear geometry to one Os2- and one O2- atom. The C–O bond length is 1.14 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C4+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C4+ atom. In each SbF6 cluster, Sb1+ is bonded in an octahedral geometry to six F1- atoms. All Sb–F bond lengths are 1.92 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Sb1+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Sb1+ atom.
