K3AsF6 is Ilmenite-like structured and crystallizes in the monoclinic C2/m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a distorted hexagonal planar geometry to two equivalent F(1) and four equivalent F(2) atoms. In the second K site, K(2) is bonded in a distorted hexagonal planar geometry to two equivalent F(1) and four equivalent F(2) atoms. As(1) is bonded in an octahedral geometry to two equivalent F(1) and four equivalent F(2) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted rectangular see-saw-like geometry to one K(2), two equivalent K(1), and one As(1) atom. In the second F site, F(2) is bonded in a distorted rectangular see-saw-like geometry to one K(2), two equivalent K(1), and one As(1) atom.

In the first K site, K(1) is bonded in a distorted hexagonal planar geometry to two equivalent F(1) and four equivalent F(2) atoms. Both K(1)-F(1) bond lengths are 2.65 Å. There are two shorter (2.66 Å) and two longer (2.80 Å) K(1)-F(2) bond lengths. In the second K site, K(2) is bonded in a distorted hexagonal planar geometry to two equivalent F(1) and four equivalent F(2) atoms. Both K(2)-F(1) bond lengths are 2.81 Å. All K(2)-F(2) bond lengths are 2.65 Å. As(1) is bonded in an octahedral geometry to two equivalent F(1) and four equivalent F(2) atoms. Both As(1)-F(1) bond lengths are 2.06 Å. All As(1)-F(2) bond lengths are 2.06 Å. There are two inequivalent F sites.
