The crystal structure described by Rb2V2MnO7 crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(3) atoms. In the second Rb site, Rb(2) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. V(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form VO4 tetrahedra that share  a cornercorner with one V(1)O4 tetrahedra and corners with two equivalent Mn(1)O4 tetrahedra. Mn(1) is bonded to four equivalent O(3) atoms to form MnO4 tetrahedra that share corners with four equivalent V(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(3) is bonded in a 2-coordinate geometry to one Rb(1), one Rb(2), one V(1), and one Mn(1) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to one Rb(2), two equivalent Rb(1), and one V(1) atom. In the third O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Rb(2) and two equivalent V(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
