Mg Ga Sn Sn
MgGaSn2 is alpha Po structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgGaSn2 cluster. Mg(1) is bonded in a 2-coordinate geometry to one Sn(1) and one Sn(2) atom. The Mg(1)-Sn(1) bond length is 1.84 Å. The Mg(1)-Sn(2) bond length is 1.58 Å. Ga(1) is bonded in a 2-coordinate geometry to one Sn(1) and one Sn(2) atom. The Ga(1)-Sn(1) bond length is 1.58 Å. The Ga(1)-Sn(2) bond length is 1.84 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 2-coordinate geometry to one Mg(1) and one Ga(1) atom. In the second Sn site, Sn(2) is bonded in a 1-coordinate geometry to one Mg(1) and one Ga(1) atom.
