Ag Ag Bi Pt
PtAg2Bi crystallizes in the monoclinic Pm space group. Pt(1) is bonded in a distorted single-bond geometry to one Ag(1) and one Bi(1) atom. The Pt(1)-Ag(1) bond length is 2.31 Å. The Pt(1)-Bi(1) bond length is 0.83 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 2-coordinate geometry to one Pt(1) and one Ag(2) atom. The Ag(1)-Ag(2) bond length is 2.12 Å. In the second Ag site, Ag(2) is bonded to one Ag(1), four equivalent Ag(2), and one Bi(1) atom to form a mixture of distorted edge and corner-sharing AgAg5Bi octahedra. The corner-sharing octahedra are not tilted. All Ag(2)-Ag(2) bond lengths are 3.17 Å. The Ag(2)-Bi(1) bond length is 3.11 Å. Bi(1) is bonded in a single-bond geometry to one Pt(1) and one Ag(2) atom.
