The material described by Yb5(Ni2Ge5)2 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 Ge(2), and eight equivalent Ge(3) atoms. In the second Yb site, Yb(2) is bonded to four equivalent Ni(1), two equivalent Ge(1), two equivalent Ge(3), and four equivalent Ge(2) atoms to form distorted face-sharing YbNi4Ge8 cuboctahedra. In the third Yb site, Yb(3) is bonded in a 14-coordinate geometry to four equivalent Ni(1), two equivalent Ge(3), four equivalent Ge(1), and four equivalent Ge(2) atoms. Ni(1) is bonded in a 10-coordinate geometry to one Yb(1), two equivalent Yb(2), two equivalent Yb(3), one Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Yb(2), four equivalent Yb(3), two equivalent Ni(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 10-coordinate geometry to one Yb(1), two equivalent Yb(2), two equivalent Yb(3), two equivalent Ni(1), one Ge(2), and two equivalent Ge(3) atoms. In the third Ge site, Ge(3) is bonded in a 10-coordinate geometry to one Yb(2), one Yb(3), two equivalent Yb(1), two equivalent Ni(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. is represented by the CIF card [CIF]
