La La Y Sn
La2YSn crystallizes in the monoclinic Cm space group. La(1) is bonded in a 12-coordinate geometry to four equivalent La(1), four equivalent Y(1), and four equivalent Sn(1) atoms. There are a spread of La(1)-La(1) bond distances ranging from 3.10-3.82 Å. There are a spread of La(1)-Y(1) bond distances ranging from 3.16-3.92 Å. There are a spread of La(1)-Sn(1) bond distances ranging from 3.16-3.92 Å. Y(1) is bonded in a 12-coordinate geometry to eight equivalent La(1) and four equivalent Sn(1) atoms. There are a spread of Y(1)-Sn(1) bond distances ranging from 3.10-3.82 Å. Sn(1) is bonded to eight equivalent La(1) and four equivalent Y(1) atoms to form a mixture of distorted face and corner-sharing SnLa8Y4 cuboctahedra.
