Ag Bi Os Os
Os2AgBi crystallizes in the monoclinic Cm space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded to one Os(2), six equivalent Os(1), and one Bi(1) atom to form a mixture of distorted corner and edge-sharing OsBiOs7 hexagonal bipyramids. The Os(1)-Os(2) bond length is 2.41 Å. All Os(1)-Os(1) bond lengths are 3.07 Å. The Os(1)-Bi(1) bond length is 3.29 Å. In the second Os site, Os(2) is bonded in a single-bond geometry to one Os(1) and one Ag(1) atom. The Os(2)-Ag(1) bond length is 1.40 Å. Ag(1) is bonded in a distorted linear geometry to one Os(2) and one Bi(1) atom. The Ag(1)-Bi(1) bond length is 1.89 Å. Bi(1) is bonded in a distorted single-bond geometry to one Os(1) and one Ag(1) atom.
