The crystal structure described by K3IrF6 is Ilmenite-like structured and crystallizes in the triclinic P-1 space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a distorted hexagonal planar geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. In the second K site, K(2) is bonded in a distorted hexagonal planar geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. In the third K site, K(3) is bonded in a distorted hexagonal planar geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. Ir(1) is bonded in an octahedral geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted rectangular see-saw-like geometry to one K(1), one K(2), one K(3), and one Ir(1) atom. In the second F site, F(2) is bonded in a distorted rectangular see-saw-like geometry to one K(1), one K(2), one K(3), and one Ir(1) atom. In the third F site, F(3) is bonded in a distorted rectangular see-saw-like geometry to one K(1), one K(2), one K(3), and one Ir(1) atom. is represented by the CIF card [CIF]
