Rb6OBr4 crystallizes in the trigonal R-3c space group. Rb(1) is bonded in a 6-coordinate geometry to one O(1), one Br(1), and four equivalent Br(2) atoms. O(1) is bonded in an octahedral geometry to six equivalent Rb(1) atoms. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 6-coordinate geometry to six equivalent Rb(1) atoms. In the second Br site, Br(2) is bonded in a 8-coordinate geometry to eight equivalent Rb(1) atoms.
