SnGeCl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SnGeCl cluster. Sn(1) is bonded in a distorted single-bond geometry to one Cl(1) atom. The Sn(1)-Cl(1) bond length is 3.08 Å. Ge(1) is bonded in a single-bond geometry to one Cl(1) atom. The Ge(1)-Cl(1) bond length is 0.42 Å. Cl(1) is bonded in a single-bond geometry to one Sn(1) and one Ge(1) atom.
