The material structure described by Rb2SrP2O7 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a 10-coordinate geometry to one O(1), three equivalent O(2), three equivalent O(3), and three equivalent O(4) atoms. Sr(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form SrO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. 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 Sr(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 15-43°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Rb(1) and two equivalent P(1) atoms. In the second O site, O(2) is bonded in a 1-coordinate geometry to three equivalent Rb(1), one Sr(1), and one P(1) atom. In the third O site, O(3) is bonded in a 1-coordinate geometry to three equivalent Rb(1), one Sr(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a 1-coordinate geometry to three equivalent Rb(1), one Sr(1), and one P(1) atom. is represented by the CIF card [CIF]
