CaAgCl2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CaAgCl2 clusters. Ca(1) is bonded in a distorted L-shaped geometry to two equivalent Cl(1) atoms. Both Ca(1)-Cl(1) bond lengths are 1.81 Å. Ag(1) is bonded in a distorted L-shaped geometry to two equivalent Cl(1) atoms. Both Ag(1)-Cl(1) bond lengths are 1.81 Å. Cl(1) is bonded in a distorted L-shaped geometry to one Ca(1) and one Ag(1) atom.
