Cr Sn Ge Ge
CrSnGe2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CrSnGe2 cluster. Cr(1) is bonded in an L-shaped geometry to one Sn(1), one Ge(1), and one Ge(2) atom. The Cr(1)-Sn(1) bond length is 0.61 Å. The Cr(1)-Ge(1) bond length is 0.61 Å. The Cr(1)-Ge(2) bond length is 1.48 Å. Sn(1) is bonded in a single-bond geometry to one Cr(1) and one Ge(2) atom. The Sn(1)-Ge(2) bond length is 1.37 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a single-bond geometry to one Cr(1) and one Ge(2) atom. The Ge(1)-Ge(2) bond length is 1.37 Å. In the second Ge site, Ge(2) is bonded in a 3-coordinate geometry to one Cr(1), one Sn(1), and one Ge(1) atom.
