Title: Materials Data on KP(HO2)2 by Materials Project

Abstract

KH2PO4 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. K1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of K–O bond distances ranging from 2.75–2.91 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.51–1.65 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one P5+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted water-like geometry to one P5+ and one H1+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one P5+ atom.
