Sn Ge P P
SnGeP2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SnGeP2 cluster. Sn(1) is bonded in a single-bond geometry to one Ge(1) atom. The Sn(1)-Ge(1) bond length is 0.64 Å. Ge(1) is bonded in a 3-coordinate geometry to one Sn(1), one P(1), and one P(2) atom. The Ge(1)-P(1) bond length is 1.53 Å. The Ge(1)-P(2) bond length is 2.24 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a single-bond geometry to one Ge(1) atom. In the second P site, P(2) is bonded in a single-bond geometry to one Ge(1) atom.
