CdSi2Cl is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CdSi2Cl clusters. Cd(1) is bonded in a single-bond geometry to one Si(2) and one Cl(1) atom. The Cd(1)-Si(2) bond length is 1.38 Å. The Cd(1)-Cl(1) bond length is 0.40 Å. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a single-bond geometry to one Cl(1) atom. The Si(1)-Cl(1) bond length is 0.98 Å. In the second Si site, Si(2) is bonded in a single-bond geometry to one Cd(1) atom. Cl(1) is bonded in a linear geometry to one Cd(1) and one Si(1) atom.
