The corner-sharing octahedral tilt angles range from 32-35°. In the second Sc site, Sc(2) is bonded to one O(1), one O(4), one O(6), one O(7), and two equivalent O(8) atoms to form distorted ScO6 octahedra that share  a cornercorner with one Sc(1)O6 octahedra,  a cornercorner with one Sc(2)O6 octahedra, corners with two equivalent Ge(1)O4 tetrahedra, corners with two equivalent Ge(2)O4 tetrahedra,  an edgeedge with one Sc(1)O6 octahedra,  an edgeedge with one Sc(2)O6 octahedra, and edges with two equivalent Sc(3)O6 octahedra.

The corner-sharing octahedral tilt angles range from 44-61°. In the second Ge site, Ge(2) is bonded to one O(1), one O(2), one O(3), and one O(6) atom to form GeO4 tetrahedra that share  a cornercorner with one Sc(1)O6 octahedra, corners with two equivalent Sc(2)O6 octahedra, corners with three equivalent Sc(3)O6 octahedra, and  an edgeedge with one Sc(1)O6 octahedra.
