The compound described by Cu2Sc2Ge4O13 crystallizes in the monoclinic P2_1/m space group. Sc(1) is bonded to one O(2), one O(3), one O(6), one O(9), and two equivalent O(4) atoms to form distorted ScO6 octahedra that share  a cornercorner with one Ge(3)O4 tetrahedra, corners with two equivalent Ge(4)O4 tetrahedra, corners with three equivalent Ge(1)O4 tetrahedra, and edges with two equivalent Sc(1)O6 octahedra. Cu(1) is bonded in a square co-planar geometry to one O(3), one O(9), and two equivalent O(1) atoms. There are four inequivalent Ge sites.
