Yb3Co4Ge13 crystallizes in the cubic Pm-3n space group. Yb(1) is bonded in a 16-coordinate geometry to four equivalent Co(1) and twelve equivalent Ge(2) atoms. Co(1) is bonded in a 9-coordinate geometry to three equivalent Yb(1) and six equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 2-coordinate geometry to three equivalent Yb(1), two equivalent Co(1), and one Ge(1) atom. In the second Ge site, Ge(1) is bonded in a cuboctahedral geometry to twelve equivalent Ge(2) atoms.
