The material structure described by Yb5Co4Ge10 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 Co(1), four equivalent Ge(2), and eight equivalent Ge(3) atoms. In the second Yb site, Yb(2) is bonded to four equivalent Co(1), two equivalent Ge(1), two equivalent Ge(3), and four equivalent Ge(2) atoms to form distorted face-sharing YbCo4Ge8 cuboctahedra. In the third Yb site, Yb(3) is bonded in a 14-coordinate geometry to four equivalent Co(1), two equivalent Ge(3), four equivalent Ge(1), and four equivalent Ge(2) atoms. Co(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 Co(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 Co(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 Co(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. is represented by the CIF card [CIF]
