NaVCSO7 crystallizes in the monoclinic P2_1 space group. Na(1) is bonded in a 4-coordinate geometry to one O(1), one O(2), one O(3), and one O(5) atom. V(1) is bonded to one O(2), one O(3), one O(4), one O(5), one O(6), and one O(7) atom to form VO6 octahedra that share corners with four equivalent S(1)O4 tetrahedra.
