Fe Fe Os Cl
OsFe2Cl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one OsFe2Cl cluster. Os(1) is bonded in a distorted single-bond geometry to one Fe(2) atom. The Os(1)-Fe(2) bond length is 1.19 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a distorted single-bond geometry to one Cl(1) atom. The Fe(1)-Cl(1) bond length is 1.90 Å. In the second Fe site, Fe(2) is bonded in a distorted single-bond geometry to one Os(1) and one Cl(1) atom. The Fe(2)-Cl(1) bond length is 0.73 Å. Cl(1) is bonded in a distorted single-bond geometry to one Fe(1) and one Fe(2) atom.
