RbSb2F7 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 10-coordinate geometry to one F(2), one F(3), one F(6), one F(7), three equivalent F(4), and three equivalent F(5) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 6-coordinate geometry to one F(4), one F(5), one F(6), one F(7), and two equivalent F(3) atoms. In the second Sb site, Sb(2) is bonded in a 5-coordinate geometry to one F(2), one F(6), one F(7), and two equivalent F(1) atoms. There are seven inequivalent F sites.
