Yb5Sn3 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a distorted square co-planar geometry to two equivalent Sn(1) and four equivalent Sn(2) atoms. In the second Yb site, Yb(2) is bonded to two equivalent Sn(1) and three equivalent Sn(2) atoms to form a mixture of distorted edge, corner, and face-sharing YbSn5 trigonal bipyramids. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 10-coordinate geometry to two equivalent Yb(1) and eight equivalent Yb(2) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent Yb(1), six equivalent Yb(2), and one Sn(2) atom.
Yb5Sn3 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a distorted square co-planar geometry to two equivalent Sn(1) and four equivalent Sn(2) atoms. Both Yb(1)-Sn(1) bond lengths are 3.77 Å. All Yb(1)-Sn(2) bond lengths are 3.18 Å. In the second Yb site, Yb(2) is bonded to two equivalent Sn(1) and three equivalent Sn(2) atoms to form a mixture of distorted edge, corner, and face-sharing YbSn5 trigonal bipyramids. Both Yb(2)-Sn(1) bond lengths are 3.39 Å. There is one shorter (3.10 Å) and two longer (3.26 Å) Yb(2)-Sn(2) bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 10-coordinate geometry to two equivalent Yb(1) and eight equivalent Yb(2) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent Yb(1), six equivalent Yb(2), and one Sn(2) atom. The Sn(2)-Sn(2) bond length is 2.85 Å.
