Cd Sn Sn As
CdSn2As crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CdSn2As cluster. Cd(1) is bonded in a single-bond geometry to one Sn(2) and one As(1) atom. The Cd(1)-Sn(2) bond length is 2.80 Å. The Cd(1)-As(1) bond length is 0.84 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a single-bond geometry to one As(1) atom. The Sn(1)-As(1) bond length is 1.97 Å. In the second Sn site, Sn(2) is bonded in a distorted single-bond geometry to one Cd(1) atom. As(1) is bonded in a distorted single-bond geometry to one Cd(1) and one Sn(1) atom.
