Na Na Sn Os
Na2OsSn crystallizes in the triclinic P1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 4-coordinate geometry to one Na(2), two equivalent Os(1), and one Sn(1) atom. The Na(1)-Na(2) bond length is 1.85 Å. There is one shorter (2.29 Å) and one longer (2.50 Å) Na(1)-Os(1) bond length. The Na(1)-Sn(1) bond length is 2.41 Å. In the second Na site, Na(2) is bonded in a distorted single-bond geometry to one Na(1), one Os(1), and two equivalent Sn(1) atoms. The Na(2)-Os(1) bond length is 1.52 Å. There is one shorter (2.08 Å) and one longer (2.50 Å) Na(2)-Sn(1) bond length. Os(1) is bonded in a distorted single-bond geometry to one Na(2), two equivalent Na(1), and one Sn(1) atom. The Os(1)-Sn(1) bond length is 2.98 Å. Sn(1) is bonded in a 4-coordinate geometry to one Na(1), two equivalent Na(2), and one Os(1) atom.
