The material structure described by RbBO2 crystallizes in the trigonal R-3c space group. Rb(1) is bonded to two equivalent O(2) and five equivalent O(1) atoms to form a mixture of distorted edge, face, and corner-sharing RbO7 pentagonal bipyramids. B(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to five equivalent Rb(1) and one B(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Rb(1) and two equivalent B(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
