Materials Data on KBePO4 by Materials Project
KBePO4 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. K1+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of K–O bond distances ranging from 2.78–3.37 Å. Be2+ is bonded to four O2- atoms to form BeO4 tetrahedra that share corners with four equivalent PO4 tetrahedra. There are a spread of Be–O bond distances ranging from 1.62–1.66 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent BeO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.53–1.56 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent K1+, one Be2+, and one P5+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to three equivalent K1+, one Be2+, and one P5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to three equivalent K1+, one Be2+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a linear geometry to three equivalent K1+, one Be2+, and one P5+ atom.
