Sc(CrGe)6 crystallizes in the hexagonal P6/mmm space group. Sc(1) is bonded to two equivalent Ge(3) and six equivalent Ge(1) atoms to form edge-sharing ScGe8 hexagonal bipyramids. Cr(1) is bonded in a 6-coordinate geometry to two equivalent 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 three equivalent Sc(1) and six equivalent Cr(1) atoms. In the second Ge site, Ge(2) is bonded in a 6-coordinate geometry to six equivalent Cr(1) atoms. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Sc(1), six equivalent Cr(1), and one Ge(3) atom.
