The material described by Rb12Sn2Bi6O crystallizes in the trigonal P-3m1 space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 14-coordinate geometry to two equivalent Rb(2), four equivalent Rb(1), two equivalent Sn(1), and six equivalent Bi(1) atoms. In the second Rb site, Rb(2) is bonded in a distorted single-bond geometry to two equivalent Rb(1), four equivalent Bi(1), and one O(1) atom. Sn(1) is bonded in a distorted trigonal planar geometry to six equivalent Rb(1) and three equivalent Bi(1) atoms. Bi(1) is bonded in a 11-coordinate geometry to four equivalent Rb(2), six equivalent Rb(1), and one Sn(1) atom. O(1) is bonded in an octahedral geometry to six equivalent Rb(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
