KSb4F13 crystallizes in the tetragonal I-4 space group. K(1) is bonded in a 8-coordinate geometry to four equivalent F(1) and four equivalent F(2) atoms. Sb(1) is bonded in a 3-coordinate geometry to one F(1), one F(3), one F(4), and two equivalent F(2) atoms. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to one K(1) and one Sb(1) atom. In the second F site, F(2) is bonded in a 3-coordinate geometry to one K(1) and two equivalent Sb(1) atoms. In the third F site, F(3) is bonded in a tetrahedral geometry to four equivalent Sb(1) atoms. In the fourth F site, F(4) is bonded in a single-bond geometry to one Sb(1) atom.
