CrAs2Cl is Cyanogen Chloride-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CrAs2Cl cluster. Cr(1) is bonded in a linear geometry to one As(1) and one As(2) atom. The Cr(1)-As(1) bond length is 1.51 Å. The Cr(1)-As(2) bond length is 1.51 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in a single-bond geometry to one Cr(1) atom. In the second As site, As(2) is bonded in a linear geometry to one Cr(1) and one Cl(1) atom. The As(2)-Cl(1) bond length is 1.39 Å. Cl(1) is bonded in a single-bond geometry to one As(2) atom.
