The compound described by Rb2CoO3 crystallizes in the orthorhombic Cmc2_1 space group. Rb(1) is bonded in a 7-coordinate geometry to three equivalent O(1) and four equivalent O(2) atoms. Co(1) is bonded to one O(1) and four equivalent O(2) atoms to form distorted edge-sharing CoO5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to six equivalent Rb(1) and one Co(1) atom. In the second O site, O(2) is bonded in a distorted water-like geometry to four equivalent Rb(1) and two equivalent Co(1) atoms. is represented by the CIF card [CIF]
