Ba Cd Cd Sn
BaCd2Sn crystallizes in the monoclinic Cm space group. Ba(1) is bonded to eight equivalent Cd(1) and four equivalent Sn(1) atoms to form a mixture of face and corner-sharing BaCd8Sn4 cuboctahedra. There are a spread of Ba(1)-Cd(1) bond distances ranging from 3.26-3.83 Å. There are a spread of Ba(1)-Sn(1) bond distances ranging from 3.25-3.73 Å. Cd(1) is bonded in a 10-coordinate geometry to four equivalent Ba(1), three equivalent Cd(1), and three equivalent Sn(1) atoms. There is one shorter (3.25 Å) and two longer (3.50 Å) Cd(1)-Cd(1) bond lengths. There are a spread of Cd(1)-Sn(1) bond distances ranging from 3.26-3.61 Å. Sn(1) is bonded in a 6-coordinate geometry to four equivalent Ba(1) and six equivalent Cd(1) atoms.
