NaSc(WO4)2 is Hydrophilite-derived structured and crystallizes in the monoclinic P2/c space group. Na(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form NaO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and edges with two equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-56°. Sc(1) is bonded to two equivalent O(3) and four equivalent O(4) atoms to form ScO6 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 47-56°. W(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form distorted WO6 octahedra that share corners with four equivalent Na(1)O6 octahedra, corners with four equivalent Sc(1)O6 octahedra, and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-56°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one W(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Na(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) and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to two equivalent Sc(1) and one W(1) atom.
