ScPHO4F3 crystallizes in the monoclinic C2/c space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent F(2) atoms to form ScO4F2 octahedra that share corners with four equivalent P(1)O4 tetrahedra. Both Sc(1)-O(1) bond lengths are 2.12 Å. Both Sc(1)-O(2) bond lengths are 2.06 Å. Both Sc(1)-F(2) bond lengths are 2.03 Å. In the second Sc site, Sc(2) is bonded to two equivalent O(3), two equivalent F(1), and two equivalent F(3) atoms to form ScO2F4 octahedra that share corners with two equivalent P(1)O4 tetrahedra. Both Sc(2)-O(3) bond lengths are 2.09 Å. Both Sc(2)-F(1) bond lengths are 2.02 Å. Both Sc(2)-F(3) bond lengths are 1.99 Å. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share  a cornercorner with one Sc(2)O2F4 octahedra and corners with two equivalent Sc(1)O4F2 octahedra. The corner-sharing octahedral tilt angles range from 21-40°. The P(1)-O(1) bond length is 1.52 Å. The P(1)-O(2) bond length is 1.51 Å. The P(1)-O(3) bond length is 1.52 Å. The P(1)-O(4) bond length is 1.56 Å. H(1) is bonded in a single-bond geometry to one O(4) atom. The H(1)-O(4) bond length is 0.71 Å. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Sc(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Sc(1) and one P(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Sc(2) and one P(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one P(1) and one H(1) atom. There are three inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one Sc(2) atom. In the second F site, F(3) is bonded in a single-bond geometry to one Sc(2) atom. In the third F site, F(2) is bonded in a single-bond geometry to one Sc(1) atom. Linkers: 8 [O]P([O])(=O)O.
