Mg Sn Sn Cl
MgSn2Cl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgSn2Cl cluster. Mg(1) is bonded in a single-bond geometry to one Sn(2) and one Cl(1) atom. The Mg(1)-Sn(2) bond length is 3.48 Å. The Mg(1)-Cl(1) bond length is 0.45 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted single-bond geometry to one Sn(2) atom. The Sn(1)-Sn(2) bond length is 2.22 Å. In the second Sn site, Sn(2) is bonded in a 2-coordinate geometry to one Mg(1) and one Sn(1) atom. Cl(1) is bonded in a single-bond geometry to one Mg(1) atom.
