Ag Ag Bi Cl
Ag2BiCl crystallizes in the trigonal R3m space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to one Bi(1) and three equivalent Cl(1) atoms to form distorted corner-sharing AgBiCl3 tetrahedra. The Ag(1)-Bi(1) bond length is 2.48 Å. All Ag(1)-Cl(1) bond lengths are 3.07 Å. In the second Ag site, Ag(2) is bonded in a distorted linear geometry to one Bi(1) and one Cl(1) atom. The Ag(2)-Bi(1) bond length is 2.48 Å. The Ag(2)-Cl(1) bond length is 2.48 Å. Bi(1) is bonded in a 5-coordinate geometry to one Ag(1), one Ag(2), and three equivalent Cl(1) atoms. All Bi(1)-Cl(1) bond lengths are 3.05 Å. Cl(1) is bonded in a 7-coordinate geometry to one Ag(2), three equivalent Ag(1), and three equivalent Bi(1) atoms.
