Na Ag Os Os
NaOs2Ag crystallizes in the monoclinic Cm space group. Na(1) is bonded in a single-bond geometry to one Os(2) and one Ag(1) atom. The Na(1)-Os(2) bond length is 2.76 Å. The Na(1)-Ag(1) bond length is 0.90 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded to one Os(2), four equivalent Os(1), and one Ag(1) atom to form a mixture of distorted edge and corner-sharing OsAgOs5 octahedra. The corner-sharing octahedra are not tilted. The Os(1)-Os(2) bond length is 2.98 Å. All Os(1)-Os(1) bond lengths are 2.61 Å. The Os(1)-Ag(1) bond length is 3.60 Å. In the second Os site, Os(2) is bonded in a distorted single-bond geometry to one Na(1) and one Os(1) atom. Ag(1) is bonded in a single-bond geometry to one Na(1) and one Os(1) atom.
