Materials Data on MgPHO9 by Materials Project

MgO6HPO3 crystallizes in the triclinic P1 space group. The structure is three-dimensional and consists of one phosphonic acid molecule and one MgO6 framework. In the MgO6 framework, Mg is bonded in an octahedral geometry to six O atoms. There are a spread of Mg–O bond distances ranging from 2.21–2.28 Å. There are six inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to one Mg and one O atom. The O–O bond length is 1.27 Å. In the second O site, O is bonded in a distorted bent 150 degrees geometry to one Mg and one O atom. The O–O bond length is 1.26 Å. In the third O site, O is bonded in a distorted bent 120 degrees geometry to one Mg and one O atom. The O–O bond length is 1.27 Å. In the fourth O site, O is bonded in a distorted bent 120 degrees geometry to one Mg and one O atom. In the fifth O site, O is bonded in a bent 120 degrees geometry to one Mg and one O atom. In the sixth O site, O is bonded in a distorted bent 120 degrees geometry to one Mg and one O atom.
