The material described by RbBF4 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 12-coordinate geometry to three equivalent F(2), three equivalent F(3), and six equivalent F(1) atoms. B(1) is bonded in a tetrahedral geometry to one F(2), one F(3), and two equivalent F(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to three equivalent Rb(1) and one B(1) atom. In the second F site, F(2) is bonded in a single-bond geometry to three equivalent Rb(1) and one B(1) atom. In the third F site, F(3) is bonded in a single-bond geometry to three equivalent Rb(1) and one B(1) atom. is represented by the CIF file [CIF]
