K3DyF6 crystallizes in the tetragonal I4/mmm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 4-coordinate geometry to four equivalent F(1) atoms. In the second K site, K(2) is bonded in a linear geometry to two equivalent F(2) atoms. Dy(1) is bonded in an octahedral geometry to two equivalent F(2) and four equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to two equivalent K(1) and one Dy(1) atom. In the second F site, F(2) is bonded in a linear geometry to one K(2) and one Dy(1) atom.
