Ba Os
BaOs crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BaOs clusters. Ba(1) is bonded in a distorted single-bond geometry to one Os(1) atom. The Ba(1)-Os(1) bond length is 2.21 Å. Os(1) is bonded in a distorted single-bond geometry to one Ba(1) atom.
