Zn Ag Ag Bi
Ag2ZnBi crystallizes in the triclinic P1 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 7-coordinate geometry to two equivalent Ag(1), two equivalent Ag(2), and three equivalent Bi(1) atoms. Both Ag(1)-Ag(1) bond lengths are 3.22 Å. There is one shorter (2.65 Å) and one longer (3.21 Å) Ag(1)-Ag(2) bond length. There are a spread of Ag(1)-Bi(1) bond distances ranging from 2.68-3.51 Å. In the second Ag site, Ag(2) is bonded in a 2-coordinate geometry to two equivalent Ag(1) and two equivalent Zn(1) atoms. There is one shorter (2.47 Å) and one longer (2.68 Å) Ag(2)-Zn(1) bond length. Zn(1) is bonded in a single-bond geometry to two equivalent Ag(2) and one Bi(1) atom. The Zn(1)-Bi(1) bond length is 0.74 Å. Bi(1) is bonded in a single-bond geometry to three equivalent Ag(1) and one Zn(1) atom.
