The material structure described by Rb2TeW3O12 crystallizes in the trigonal P31c space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 3-coordinate geometry to three equivalent O(2) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(3) atoms. W(1) is bonded to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 30-41°. Te(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Rb(2) and one W(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Rb(1), one W(1), and one Te(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one Rb(2) and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
