The compound described by Yb5Ni4Sn10 crystallizes in the tetragonal P4/mbm space group. There are three inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 16-coordinate geometry to four equivalent Ni(1), four equivalent Sn(1), and eight equivalent Sn(2) atoms. In the second Yb site, Yb(2) is bonded to four equivalent Ni(1), two equivalent Sn(2), two equivalent Sn(3), and four equivalent Sn(1) atoms to form distorted face-sharing YbNi4Sn8 cuboctahedra. In the third Yb site, Yb(3) is bonded in a 14-coordinate geometry to four equivalent Ni(1), two equivalent Sn(2), four equivalent Sn(1), and four equivalent Sn(3) atoms. Ni(1) is bonded in a 10-coordinate geometry to one Yb(1), two equivalent Yb(2), two equivalent Yb(3), one Sn(3), two equivalent Sn(1), and two equivalent Sn(2) atoms. There are three inequivalent Sn sites. In the first Sn site, Sn(3) is bonded in a 9-coordinate geometry to two equivalent Yb(2), four equivalent Yb(3), two equivalent Ni(1), and one Sn(3) atom. In the second Sn site, Sn(1) is bonded in a 10-coordinate geometry to one Yb(1), two equivalent Yb(2), two equivalent Yb(3), two equivalent Ni(1), one Sn(1), and two equivalent Sn(2) atoms. In the third Sn site, Sn(2) is bonded in a 5-coordinate geometry to one Yb(2), one Yb(3), two equivalent Yb(1), two equivalent Ni(1), and two equivalent Sn(1) atoms. is represented by the CIF file [CIF]
