The compound described by RbNaTiO3 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. Na(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(1) atoms. Ti(1) is bonded to one O(2) and four equivalent O(1) atoms to form distorted edge-sharing TiO5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Na(1) and two equivalent Ti(1) atoms. In the second O site, O(2) is bonded in a 6-coordinate geometry to four equivalent Rb(1), one Na(1), and one Ti(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
