Fe Ag Bi Bi
FeAgBi2 crystallizes in the monoclinic Cm space group. Fe(1) is bonded in a single-bond geometry to one Ag(1) and one Bi(1) atom. The Fe(1)-Ag(1) bond length is 3.51 Å. The Fe(1)-Bi(1) bond length is 1.62 Å. Ag(1) is bonded to one Fe(1), six equivalent Ag(1), and one Bi(2) atom to form a mixture of distorted corner and edge-sharing AgFeAg6Bi hexagonal bipyramids. All Ag(1)-Ag(1) bond lengths are 3.38 Å. The Ag(1)-Bi(2) bond length is 3.65 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a linear geometry to one Fe(1) and one Bi(2) atom. The Bi(1)-Bi(2) bond length is 0.95 Å. In the second Bi site, Bi(2) is bonded in a single-bond geometry to one Ag(1) and one Bi(1) atom.
