Na Li Os Os
NaLiOs2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaLiOs2 cluster. Na(1) is bonded in a 2-coordinate geometry to one Os(1) and one Os(2) atom. The Na(1)-Os(1) bond length is 1.50 Å. The Na(1)-Os(2) bond length is 2.08 Å. Li(1) is bonded in a distorted single-bond geometry to one Os(1) atom. The Li(1)-Os(1) bond length is 2.04 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a distorted bent 150 degrees geometry to one Na(1) and one Li(1) atom. In the second Os site, Os(2) is bonded in a distorted single-bond geometry to one Na(1) atom.
