Yb2Sn crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 14-coordinate geometry to two equivalent Yb(1), six equivalent Yb(2), and six equivalent Sn(1) atoms. In the second Yb site, Yb(2) is bonded to six equivalent Yb(1) and five equivalent Sn(1) atoms to form a mixture of distorted corner and face-sharing YbYb6Sn5 trigonal bipyramids. Sn(1) is bonded in a 11-coordinate geometry to five equivalent Yb(2) and six equivalent Yb(1) atoms.
Yb2Sn crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 14-coordinate geometry to two equivalent Yb(1), six equivalent Yb(2), and six equivalent Sn(1) atoms. Both Yb(1)-Yb(1) bond lengths are 3.48 Å. All Yb(1)-Yb(2) bond lengths are 3.51 Å. All Yb(1)-Sn(1) bond lengths are 3.51 Å. In the second Yb site, Yb(2) is bonded to six equivalent Yb(1) and five equivalent Sn(1) atoms to form a mixture of distorted corner and face-sharing YbYb6Sn5 trigonal bipyramids. There are three shorter (3.05 Å) and two longer (3.48 Å) Yb(2)-Sn(1) bond lengths. Sn(1) is bonded in a 11-coordinate geometry to five equivalent Yb(2) and six equivalent Yb(1) atoms.
