Cd Cd Sn Br
Cd2SnBr is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Cd2SnBr clusters. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a single-bond geometry to one Br(1) atom. The Cd(1)-Br(1) bond length is 0.34 Å. In the second Cd site, Cd(2) is bonded in a single-bond geometry to one Sn(1) atom. The Cd(2)-Sn(1) bond length is 0.78 Å. Sn(1) is bonded in a linear geometry to one Cd(2) and one Br(1) atom. The Sn(1)-Br(1) bond length is 0.44 Å. Br(1) is bonded in a linear geometry to one Cd(1) and one Sn(1) atom.
