AgCl2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one AgCl2 cluster. Ag(1) is bonded in a 2-coordinate geometry to one Cl(2) and two equivalent Cl(1) atoms. The Ag(1)-Cl(2) bond length is 2.26 Å. There is one shorter (0.45 Å) and one longer (1.27 Å) Ag(1)-Cl(1) bond length. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted L-shaped geometry to two equivalent Ag(1) atoms. In the second Cl site, Cl(2) is bonded in a distorted single-bond geometry to one Ag(1) atom.
