Rb2TiOF5 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 5-coordinate geometry to one O(1), two equivalent F(1), and two equivalent F(2) atoms. Ti(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form corner-sharing TiF6 octahedra. The corner-sharing octahedral tilt angles are 1°. O(1) is bonded in an L-shaped geometry to two equivalent Rb(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one Ti(1) atom. In the second F site, F(2) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one Ti(1) atom. In the third F site, F(3) is bonded in a linear geometry to two equivalent Ti(1) atoms.
