Cd Co Sn Sn
CoCdSn2 crystallizes in the monoclinic Cm space group. Co(1) is bonded in a 5-coordinate geometry to one Cd(1) and four equivalent Sn(2) atoms. The Co(1)-Cd(1) bond length is 2.33 Å. There are a spread of Co(1)-Sn(2) bond distances ranging from 1.99-2.65 Å. Cd(1) is bonded in a single-bond geometry to one Co(1) and one Sn(1) atom. The Cd(1)-Sn(1) bond length is 3.51 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to one Cd(1), one Sn(2), and four equivalent Sn(1) atoms to form a mixture of distorted corner and edge-sharing SnCdSn5 octahedra. The corner-sharing octahedra are not tilted. The Sn(1)-Sn(2) bond length is 2.62 Å. All Sn(1)-Sn(1) bond lengths are 3.15 Å. In the second Sn site, Sn(2) is bonded in a 5-coordinate geometry to four equivalent Co(1) and one Sn(1) atom.
