K3CrF6 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. Cr(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 1-coordinate geometry to one K(1), one K(2), one K(3), and one Cr(1) atom. In the second F site, F(2) is bonded in a 4-coordinate geometry to one K(1), one K(2), one K(3), and one Cr(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 Cr(1) atom.
