The compound described by Yb2CuGe6 crystallizes in the monoclinic C2/m space group. Yb(1) is bonded to two equivalent Cu(1), one Ge(1), one Ge(2), two equivalent Ge(5), three equivalent Ge(3), and three equivalent Ge(4) atoms to form a mixture of distorted corner, edge, and face-sharing YbCu2Ge10 cuboctahedra. Cu(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1), one Ge(1), one Ge(2), one Ge(4), and two equivalent Ge(5) atoms. There are five inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 6-coordinate geometry to two equivalent Yb(1), one Cu(1), one Ge(1), and two equivalent Ge(5) atoms. In the second Ge site, Ge(2) is bonded in a 6-coordinate geometry to two equivalent Yb(1), one Cu(1), one Ge(2), and two equivalent Ge(5) atoms. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to six equivalent Yb(1), one Ge(3), and one Ge(4) atom. In the fourth Ge site, Ge(4) is bonded in a 9-coordinate geometry to six equivalent Yb(1), one Cu(1), one Ge(3), and one Ge(4) atom. In the fifth Ge site, Ge(5) is bonded in a 6-coordinate geometry to two equivalent Yb(1), one Cu(1), one Ge(1), one Ge(2), and one Ge(5) atom. is represented by the Crystallographic Information File (CIF) [CIF]
