CrSiCl2 crystallizes in the monoclinic Pm space group. Cr(1) is bonded in a distorted single-bond geometry to one Si(1) and four equivalent Cl(1) atoms. The Cr(1)-Si(1) bond length is 0.96 Å. There are two shorter (2.87 Å) and two longer (3.00 Å) Cr(1)-Cl(1) bond lengths. Si(1) is bonded in a single-bond geometry to one Cr(1) and two equivalent Cl(1) atoms. Both Si(1)-Cl(1) bond lengths are 2.87 Å. Cl(1) is bonded in a 4-coordinate geometry to two equivalent Cr(1), one Si(1), and one Cl(1) atom. The Cl(1)-Cl(1) bond length is 1.13 Å.
