RbTiZnOF5 crystallizes in the orthorhombic Imma space group. Rb(1) is bonded to one F(2) and four equivalent F(1) atoms to form RbF5 square pyramids that share corners with four equivalent Ti(1)O2F4 octahedra and corners with six equivalent Zn(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 64-69°. Ti(1) is bonded to two equivalent O(1) and four equivalent F(1) atoms to form TiO2F4 octahedra that share corners with two equivalent Ti(1)O2F4 octahedra, corners with four equivalent Zn(1)F6 octahedra, and corners with four equivalent Rb(1)F5 square pyramids. The corner-sharing octahedral tilt angles range from 23-48°. Zn(1) is bonded to two equivalent F(2) and four equivalent F(1) atoms to form ZnF6 octahedra that share corners with two equivalent Zn(1)F6 octahedra, corners with four equivalent Ti(1)O2F4 octahedra, and corners with six equivalent Rb(1)F5 square pyramids. The corner-sharing octahedral tilt angles range from 47-48°. O(1) is bonded in a bent 150 degrees geometry to two equivalent Ti(1) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 3-coordinate geometry to one Rb(1), one Ti(1), and one Zn(1) atom. In the second F site, F(2) is bonded in a 2-coordinate geometry to one Rb(1) and two equivalent Zn(1) atoms.
