Materials Data on Co2SnC8SeO8 by Materials Project
(Co(CO)4)2SnSe crystallizes in the orthorhombic Fddd space group. The structure is zero-dimensional and consists of thirty-two Co(CO)4 clusters and eight SnSe clusters. In each Co(CO)4 cluster, Co2+ is bonded in a trigonal pyramidal geometry to four C+1.25+ atoms. There is two shorter (1.77 Å) and two longer (1.78 Å) Co–C bond length. There are four inequivalent C+1.25+ sites. In the first C+1.25+ site, C+1.25+ is bonded in a linear geometry to one Co2+ and one O2- atom. The C–O bond length is 1.16 Å. In the second C+1.25+ site, C+1.25+ is bonded in a linear geometry to one Co2+ and one O2- atom. The C–O bond length is 1.16 Å. In the third C+1.25+ site, C+1.25+ is bonded in a linear geometry to one Co2+ and one O2- atom. The C–O bond length is 1.16 Å. In the fourth C+1.25+ site, C+1.25+ is bonded in a linear geometry to one Co2+ and one O2- atom. The C–O bond length is 1.16 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C+1.25+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+1.25+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one C+1.25+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one C+1.25+ atom. In each SnSe cluster, Sn4+ is bonded in an L-shaped geometry to two equivalent Se2- atoms. Both Sn–Se bond lengths are 2.60 Å. Se2- is bonded in an L-shaped geometry to two equivalent Sn4+ atoms.
