The material structure described by Yb(FeGe)6 crystallizes in the hexagonal P6/mmm space group. Yb(1) is bonded to twelve equivalent Fe(1), two equivalent Ge(3), and six equivalent Ge(1) atoms to form distorted YbFe12Ge8 hexagonal bipyramids that share faces with twenty-four equivalent Fe(1)Yb2Fe4Ge6 cuboctahedra and faces with six equivalent Yb(1)Fe12Ge8 hexagonal bipyramids. Fe(1) is bonded to two equivalent Yb(1), four equivalent Fe(1), two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms to form distorted FeYb2Fe4Ge6 cuboctahedra that share corners with fourteen equivalent Fe(1)Yb2Fe4Ge6 cuboctahedra, edges with seven equivalent Fe(1)Yb2Fe4Ge6 cuboctahedra, faces with nine equivalent Fe(1)Yb2Fe4Ge6 cuboctahedra, and faces with four equivalent Yb(1)Fe12Ge8 hexagonal bipyramids. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Yb(1) and six equivalent Fe(1) atoms. In the second Ge site, Ge(2) is bonded in a 6-coordinate geometry to six equivalent Fe(1) atoms. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Yb(1), six equivalent Fe(1), and one Ge(3) atom. is represented by the CIF card [CIF]
