ZnSn2Cl crystallizes in the trigonal R3m space group. Zn(1) is bonded in a linear geometry to one Sn(1) and one Sn(2) atom. The Zn(1)-Sn(1) bond length is 2.52 Å. The Zn(1)-Sn(2) bond length is 2.52 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted linear geometry to one Zn(1) and one Cl(1) atom. The Sn(1)-Cl(1) bond length is 2.52 Å. In the second Sn site, Sn(2) is bonded to one Zn(1) and three equivalent Cl(1) atoms to form distorted corner-sharing SnZnCl3 tetrahedra. All Sn(2)-Cl(1) bond lengths are 3.03 Å. Cl(1) is bonded in a 4-coordinate geometry to one Sn(1) and three equivalent Sn(2) atoms.
