The structure described by K4SnSb2F14 crystallizes in the triclinic P-1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to one F(1), one F(2), one F(3), one F(6), two equivalent F(4), and two equivalent F(7) atoms. In the second K site, K(2) is bonded in a 11-coordinate geometry to one F(2), one F(4), one F(7), two equivalent F(1), two equivalent F(3), two equivalent F(5), and two equivalent F(6) atoms. Sn(1) is bonded in an octahedral geometry to two equivalent F(2), two equivalent F(4), and two equivalent F(6) atoms. Sb(1) is bonded in a distorted rectangular see-saw-like geometry to one F(1), one F(3), one F(5), and one F(7) atom. There are seven inequivalent F sites. In the first F site, F(1) is bonded in a 4-coordinate geometry to one K(1), two equivalent K(2), and one Sb(1) atom. In the second F site, F(2) is bonded in a distorted single-bond geometry to one K(1), one K(2), and one Sn(1) atom. In the third F site, F(3) is bonded in a 4-coordinate geometry to one K(1), two equivalent K(2), and one Sb(1) atom. In the fourth F site, F(4) is bonded in a 4-coordinate geometry to one K(2), two equivalent K(1), and one Sn(1) atom. In the fifth F site, F(5) is bonded in a 3-coordinate geometry to two equivalent K(2) and one Sb(1) atom. In the sixth F site, F(6) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), and one Sn(1) atom. In the seventh F site, F(7) is bonded to one K(2), two equivalent K(1), and one Sb(1) atom to form distorted edge-sharing FK3Sb tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
