KAs(OF2)2 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 8-coordinate geometry to four equivalent O(1), two equivalent F(1), and two equivalent F(2) atoms. As(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent F(1), and two equivalent F(2) atoms. O(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one As(1) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to one K(1) and one As(1) atom. In the second F site, F(2) is bonded in a distorted single-bond geometry to one K(1) and one As(1) atom.
KAs(OF2)2 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 8-coordinate geometry to four equivalent O(1), two equivalent F(1), and two equivalent F(2) atoms. There are two shorter (2.89 Å) and two longer (3.27 Å) K(1)-O(1) bond lengths. Both K(1)-F(1) bond lengths are 2.85 Å. Both K(1)-F(2) bond lengths are 2.93 Å. As(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent F(1), and two equivalent F(2) atoms. Both As(1)-O(1) bond lengths are 1.80 Å. Both As(1)-F(1) bond lengths are 1.81 Å. Both As(1)-F(2) bond lengths are 1.80 Å. O(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one As(1) atom. There are two inequivalent F sites.
