ScP2NO8 crystallizes in the monoclinic P2_1/c space group. Sc(1) is bonded to one O(1), one O(2), one O(3), one O(5), one O(6), and one O(7) atom to form ScO6 octahedra that share corners with three equivalent P(1)O4 tetrahedra and corners with three equivalent P(2)O4 trigonal pyramids. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form distorted PO4 tetrahedra that share corners with three equivalent Sc(1)O6 octahedra.
