The material structure described by RbSc(PO4)2 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 11-coordinate geometry to one O(2), one O(3), one O(5), one O(6), one O(7), three equivalent O(4), and three equivalent O(8) atoms. 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 tetrahedra. 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 PO4 tetrahedra that share corners with three equivalent Sc(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 10-32°. In the second P site, P(2) is bonded to one O(5), one O(6), one O(7), and one O(8) atom to form PO4 tetrahedra that share corners with three equivalent Sc(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 21-45°. There are eight inequivalent O sites. In the first O site, O(5) is bonded in a distorted bent 150 degrees geometry to one Rb(1), one Sc(1), and one P(2) atom. In the second O site, O(6) is bonded in a distorted bent 150 degrees geometry to one Rb(1), one Sc(1), and one P(2) atom. In the third O site, O(7) is bonded in a 2-coordinate geometry to one Rb(1), one Sc(1), and one P(2) atom. In the fourth O site, O(8) is bonded in a single-bond geometry to three equivalent Rb(1) and one P(2) atom. In the fifth O site, O(1) is bonded in a linear geometry to one Sc(1) and one P(1) atom. In the sixth O site, O(2) is bonded in a bent 150 degrees geometry to one Rb(1), one Sc(1), and one P(1) atom. In the seventh O site, O(3) is bonded in a bent 150 degrees geometry to one Rb(1), one Sc(1), and one P(1) atom. In the eighth O site, O(4) is bonded in a distorted single-bond geometry to three equivalent Rb(1) and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
