RbLiF2 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent F(1), two equivalent F(2), and four equivalent F(3) atoms. Li(1) is bonded to one F(1), one F(2), and two equivalent F(3) atoms to form a mixture of corner and edge-sharing LiF4 tetrahedra. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 120 degrees geometry to four equivalent Rb(1) and two equivalent Li(1) atoms. In the second F site, F(2) is bonded in a distorted linear geometry to four equivalent Rb(1) and two equivalent Li(1) atoms. In the third F site, F(3) is bonded in a 2-coordinate geometry to four equivalent Rb(1) and two equivalent Li(1) atoms.
