AgBi2Cl crystallizes in the monoclinic Cm space group. Ag(1) is bonded in a single-bond geometry to four equivalent Bi(1) and one Cl(1) atom. There are two shorter (2.62 Å) and two longer (3.19 Å) Ag(1)-Bi(1) bond lengths. The Ag(1)-Cl(1) bond length is 1.92 Å. Bi(1) is bonded in a 7-coordinate geometry to two equivalent Ag(1), three equivalent Bi(1), and two equivalent Cl(1) atoms. There is one shorter (1.92 Å) and two longer (3.51 Å) Bi(1)-Bi(1) bond lengths. There is one shorter (2.62 Å) and one longer (3.19 Å) Bi(1)-Cl(1) bond length. Cl(1) is bonded in a distorted single-bond geometry to one Ag(1) and four equivalent Bi(1) atoms.
