CsSb2F7 crystallizes in the monoclinic C2/c space group. Cs(1) is bonded to two equivalent F(1), four equivalent F(2), and six equivalent F(3) atoms to form a mixture of distorted edge and face-sharing CsF12 cuboctahedra. Sb(1) is bonded in a 4-coordinate geometry to one F(1), one F(2), one F(3), and one F(4) atom. There are four inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one Cs(1) and one Sb(1) atom. In the second F site, F(2) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one Sb(1) atom. In the third F site, F(3) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one Sb(1) atom. In the fourth F site, F(4) is bonded in a bent 120 degrees geometry to two equivalent Sb(1) atoms.
