RbSm3F10 crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to four equivalent F(2) and twelve equivalent F(1) atoms to form distorted edge-sharing RbF16 tetrahedra. Sm(1) is bonded in a 8-coordinate geometry to four equivalent F(1) and four equivalent F(2) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to two equivalent Rb(1) and two equivalent Sm(1) atoms. In the second F site, F(2) is bonded to one Rb(1) and three equivalent Sm(1) atoms to form a mixture of corner and edge-sharing FRbSm3 tetrahedra.
