Materials Data on K2Cu(IF)2 by Materials Project
K2Cu(IF)2 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. K1+ is bonded in a distorted square co-planar geometry to two equivalent I1- and four equivalent F1- atoms. Both K–I bond lengths are 3.76 Å. All K–F bond lengths are 2.65 Å. Cu2+ is bonded in a square co-planar geometry to four equivalent I1- atoms. All Cu–I bond lengths are 2.65 Å. I1- is bonded in a distorted square co-planar geometry to two equivalent K1+ and two equivalent Cu2+ atoms. F1- is bonded in a square co-planar geometry to four equivalent K1+ atoms.
