XeCsF7 crystallizes in the cubic P2_13 space group. Xe(1) is bonded in a 7-coordinate geometry to one F(3), three equivalent F(1), and three equivalent F(2) atoms. Cs(1) is bonded in a 15-coordinate geometry to three equivalent F(3), six equivalent F(1), and six equivalent F(2) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to one Xe(1) and two equivalent Cs(1) atoms. In the second F site, F(2) is bonded in a distorted single-bond geometry to one Xe(1) and two equivalent Cs(1) atoms. In the third F site, F(3) is bonded in a distorted single-bond geometry to one Xe(1) and three equivalent Cs(1) atoms.
