Materials Data on MgBP(H3O4)2 by Materials Project
MgBP(H3O4)2 crystallizes in the trigonal R-3c space group. The structure is three-dimensional and consists of two MgBP(H3O4)2 frameworks. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with two equivalent BO4 tetrahedra and corners with two equivalent PO4 tetrahedra. There are a spread of Mg–O bond distances ranging from 2.06–2.15 Å. B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share corners with two equivalent MgO6 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles are 43°. There is two shorter (1.47 Å) and two longer (1.51 Å) B–O bond length. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent MgO6 octahedra and corners with two equivalent BO4 tetrahedra. The corner-sharing octahedral tilt angles are 45°. There is two shorter (1.53 Å) and two longer (1.57 Å) P–O bond length. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- atom. The H–O bond length is 1.01 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. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Mg2+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Mg2+, one B3+, and one H1+ atom. In the third O2- site, O2- is bonded in a distorted water-like geometry to one Mg2+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one B3+ and one P5+ atom.
