Materials Data on Co6Ge2(CO)19 by Materials Project
Co2(CO)5(Co(CO)4)2(Co(CO)3)2(Ge)2 crystallizes in the orthorhombic Cmce space group. The structure is zero-dimensional and consists of sixteen akos016035116 molecules, sixteen germanium molecules, sixteen Co(CO)4 clusters, and eight Co2(CO)5 clusters. In each Co(CO)4 cluster, Co2+ is bonded in a trigonal pyramidal geometry to four C+0.95+ atoms. There is two shorter (1.77 Å) and two longer (1.78 Å) Co–C bond length. There are four inequivalent C+0.95+ sites. In the first C+0.95+ site, C+0.95+ 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+0.95+ site, C+0.95+ is bonded in a linear geometry to one Co2+ and one O2- atom. The C–O bond length is 1.15 Å. In the third C+0.95+ site, C+0.95+ 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+0.95+ site, C+0.95+ 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+0.95+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+0.95+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one C+0.95+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one C+0.95+ atom. In each Co2(CO)5 cluster, there are two inequivalent Co2+ sites. In the first Co2+ site, Co2+ is bonded in a distorted water-like geometry to three C+0.95+ atoms. There is two shorter (1.77 Å) and one longer (1.92 Å) Co–C bond length. In the second Co2+ site, Co2+ is bonded in a 3-coordinate geometry to three C+0.95+ atoms. There is two shorter (1.77 Å) and one longer (1.89 Å) Co–C bond length. There are three inequivalent C+0.95+ sites. In the first C+0.95+ site, C+0.95+ 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+0.95+ site, C+0.95+ 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+0.95+ site, C+0.95+ is bonded in a distorted single-bond geometry to two Co2+ and one O2- atom. The C–O bond length is 1.18 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C+0.95+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+0.95+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one C+0.95+ atom.
