The material described by Yb(CoGe)6 crystallizes in the hexagonal P6/mmm space group. Yb(1) is bonded to twelve equivalent Co(1), two equivalent Ge(3), and six equivalent Ge(1) atoms to form distorted YbCo12Ge8 hexagonal bipyramids that share faces with twenty-four equivalent Co(1)Yb2Co4Ge6 cuboctahedra and faces with six equivalent Yb(1)Co12Ge8 hexagonal bipyramids. Co(1) is bonded to two equivalent Yb(1), four equivalent Co(1), two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms to form distorted CoYb2Co4Ge6 cuboctahedra that share corners with fourteen equivalent Co(1)Yb2Co4Ge6 cuboctahedra, edges with seven equivalent Co(1)Yb2Co4Ge6 cuboctahedra, faces with nine equivalent Co(1)Yb2Co4Ge6 cuboctahedra, and faces with four equivalent Yb(1)Co12Ge8 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 Co(1) atoms. In the second Ge site, Ge(2) is bonded in a 6-coordinate geometry to six equivalent Co(1) atoms. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Yb(1), six equivalent Co(1), and one Ge(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
