ScCu(WO4)2 is Hydrophilite-derived structured and crystallizes in the monoclinic C2/c space group. Sc(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form ScO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and edges with two equivalent Cu(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-53°. W(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form distorted WO6 octahedra that share corners with four equivalent Sc(1)O6 octahedra, corners with four equivalent Cu(1)O6 octahedra, and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-55°. Cu(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form CuO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and edges with two equivalent Sc(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-55°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Sc(1), one W(1), and one Cu(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Sc(1) and two equivalent W(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Sc(1), one W(1), and one Cu(1) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to two equivalent W(1) and one Cu(1) atom.
