Materials Data on KP(HO)4 by Materials Project
KP(HO)4 crystallizes in the tetragonal I-42d space group. The structure is one-dimensional and consists of four KP(HO)4 ribbons oriented in the (0, 0, 1) direction. K1+ is bonded in a 8-coordinate geometry to four equivalent O2- atoms. All K–O bond lengths are 3.09 Å. P5+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All P–O bond lengths are 1.90 Å. H+0.50+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. O2- is bonded in a 1-coordinate geometry to one K1+, one P5+, and one H+0.50+ atom.
