The structure described by RbV2SeO7 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 9-coordinate geometry to two equivalent O(5), three equivalent O(1), and four equivalent O(2) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form distorted corner-sharing VO6 octahedra. In the second V site, V(2) is bonded to one O(4), one O(5), and two equivalent O(3) atoms to form corner-sharing VO4 tetrahedra. The corner-sharing octahedral tilt angles are 14°. Se(1) is bonded in a distorted trigonal non-coplanar geometry to one O(5) and two equivalent O(2) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Rb(1) and one V(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Rb(1), one V(1), and one Se(1) atom. In the third O site, O(3) is bonded in a linear geometry to one V(1) and one V(2) atom. In the fourth O site, O(4) is bonded in a distorted linear geometry to one V(1) and one V(2) atom. In the fifth O site, O(5) is bonded in a 2-coordinate geometry to two equivalent Rb(1), one V(2), and one Se(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
