The crystal structure described by Rb2V2Cu(PO6)2 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 10-coordinate geometry to one O(1), one O(2), one O(5), one O(6), three equivalent O(3), and three equivalent O(4) atoms. V(1) is bonded to one O(1), one O(2), one O(3), one O(4), and one O(5) atom to form distorted VO5 trigonal bipyramids that share corners with three equivalent P(1)O4 tetrahedra. Cu(1) is bonded in a square co-planar geometry to two equivalent O(5) and two equivalent O(6) atoms. P(1) is bonded to one O(1), one O(2), one O(5), and one O(6) atom to form PO4 tetrahedra that share corners with three equivalent V(1)O5 trigonal bipyramids. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Rb(1), one V(1), and one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Rb(1), one V(1), and one P(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Rb(1) and one V(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to three equivalent Rb(1) and one V(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one Rb(1), one V(1), one Cu(1), and one P(1) atom. In the sixth O site, O(6) is bonded in a distorted bent 120 degrees geometry to one Rb(1), one Cu(1), and one P(1) atom. is represented by the CIF file [CIF]
