Abstract

(Os(CO)3)4Os(CO)4 crystallizes in the trigonal P3_121 space group. The structure is zero-dimensional and consists of twelve Os(CO)3 clusters and three Os(CO)4 clusters. In each Os(CO)3 cluster, Os+1.60- is bonded in a distorted T-shaped geometry to three C+2.50+ atoms. There is one shorter (1.89 Å) and two longer (1.90 Å) Os–C bond length. There are three inequivalent C+2.50+ sites. In the first C+2.50+ site, C+2.50+ is bonded in a linear geometry to one Os+1.60- and one O2- atom. The C–O bond length is 1.16 Å. In the second C+2.50+ site, C+2.50+ is bonded in a linear geometry to one Os+1.60- and one O2- atom. The C–O bond length is 1.16 Å. In the third C+2.50+ site, C+2.50+ is bonded in a linear geometry to one Os+1.60- and one O2- atom. The C–O bond length is 1.17 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C+2.50+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+2.50+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one C+2.50+ atom. In each Os(CO)4 cluster, Os+1.60- is bonded in a see-saw-like geometry to four C+2.50+ atoms. There is two shorter (1.94 Å) and two longer (1.98 Å) Os–C bond length. There are two inequivalent C+2.50+ sites. In the first C+2.50+ site, C+2.50+ is bonded in a distorted single-bond geometry to one Os+1.60- and one O2- atom. The C–O bond length is 1.16 Å. In the second C+2.50+ site, C+2.50+ is bonded in a distorted linear geometry to one Os+1.60- and one O2- atom. The C–O bond length is 1.16 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C+2.50+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+2.50+ atom.
