Mg Zn Zn Sn
MgSn(Zn)2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one magnesium;tin molecule and one Zn cluster. In the Zn cluster, there are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a distorted single-bond geometry to one Zn(2) atom. The Zn(1)-Zn(2) bond length is 0.98 Å. In the second Zn site, Zn(2) is bonded in a distorted single-bond geometry to one Zn(1) atom.
