Sn Cl Cl
SnCl2 crystallizes in the triclinic P1 space group. Sn(1) is bonded in a 12-coordinate geometry to six equivalent Sn(1), three equivalent Cl(1), and three equivalent Cl(2) atoms. There are two shorter (2.37 Å) and four longer (2.62 Å) Sn(1)-Sn(1) bond lengths. There are a spread of Sn(1)-Cl(1) bond distances ranging from 2.96-3.05 Å. There are a spread of Sn(1)-Cl(2) bond distances ranging from 2.98-3.03 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to three equivalent Sn(1) and one Cl(2) atom. The Cl(1)-Cl(2) bond length is 0.18 Å. In the second Cl site, Cl(2) is bonded in a single-bond geometry to three equivalent Sn(1) and one Cl(1) atom.
