K2ZrF6 crystallizes in the orthorhombic Cmcm space group. K(1) is bonded in a 9-coordinate geometry to one F(1), four equivalent F(2), and four equivalent F(3) atoms. Zr(1) is bonded in a 8-coordinate geometry to two equivalent F(2), two equivalent F(3), and four equivalent F(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a 3-coordinate geometry to one K(1) and two equivalent Zr(1) atoms. In the second F site, F(2) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Zr(1) atom. In the third F site, F(3) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Zr(1) atom.
K2ZrF6 crystallizes in the orthorhombic Cmcm space group. K(1) is bonded in a 9-coordinate geometry to one F(1), four equivalent F(2), and four equivalent F(3) atoms. The K(1)-F(1) bond length is 2.80 Å. There are two shorter (2.70 Å) and two longer (2.71 Å) K(1)-F(2) bond lengths. There are two shorter (2.75 Å) and two longer (2.88 Å) K(1)-F(3) bond lengths. Zr(1) is bonded in a 8-coordinate geometry to two equivalent F(2), two equivalent F(3), and four equivalent F(1) atoms. Both Zr(1)-F(2) bond lengths are 2.10 Å. Both Zr(1)-F(3) bond lengths are 2.05 Å. There are two shorter (2.12 Å) and two longer (2.23 Å) Zr(1)-F(1) bond lengths. There are three inequivalent F sites. In the first F site, F(1) is bonded in a 3-coordinate geometry to one K(1) and two equivalent Zr(1) atoms.
