The material described by Rb2SnO3 is Krennerite-derived structured and crystallizes in the orthorhombic Cmc2_1 space group. Rb(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Sn(1) is bonded to one O(2) and four equivalent O(1) atoms to form distorted edge-sharing SnO5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Rb(1) and two equivalent Sn(1) atoms to form a mixture of distorted edge, corner, and face-sharing ORb4Sn2 octahedra. The corner-sharing octahedral tilt angles range from 36-50°. In the second O site, O(2) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one Sn(1) atom. is represented by the CIF file [CIF]
