The material structure described by Sc11Ge10 crystallizes in the tetragonal I4/mmm space group. There are four inequivalent Sc sites. In the first Sc site, Sc(1) is bonded to one Ge(1), one Ge(2), one Ge(4), and four equivalent Ge(5) atoms to form a mixture of distorted edge, corner, and face-sharing ScGe7 pentagonal bipyramids. In the second Sc site, Sc(2) is bonded in a 7-coordinate geometry to one Ge(3), two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(5) atoms. In the third Sc site, Sc(3) is bonded in a 9-coordinate geometry to one Ge(2), four equivalent Ge(3), and four equivalent Ge(5) atoms. In the fourth Sc site, Sc(4) is bonded in a 7-coordinate geometry to one Ge(4), two equivalent Ge(1), two equivalent Ge(3), and two equivalent Ge(5) atoms. There are five inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to two equivalent Sc(1), two equivalent Sc(2), and four equivalent Sc(4) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Sc(3), four equivalent Sc(1), and four equivalent Sc(2) atoms. In the third Ge site, Ge(3) is bonded in a 11-coordinate geometry to one Sc(2), two equivalent Sc(3), four equivalent Sc(4), two equivalent Ge(3), and two equivalent Ge(5) atoms. In the fourth Ge site, Ge(4) is bonded in a 8-coordinate geometry to four equivalent Sc(1) and four equivalent Sc(4) atoms. In the fifth Ge site, Ge(5) is bonded in a 9-coordinate geometry to one Sc(2), one Sc(3), two equivalent Sc(4), four equivalent Sc(1), one Ge(3), and one Ge(5) atom. is represented by the CIF file [CIF]
