Title: Materials Data on MgTi2(PO5)2 by Materials Project

Abstract

MgTi2(PO5)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with four equivalent PO4 tetrahedra. There are two shorter (2.08 Å) and four longer (2.09 Å) Mg–O bond lengths. Ti4+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ti–O bond distances ranging from 1.74–2.26 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent MgO6 octahedra. The corner-sharing octahedra tilt angles range from 43–48°. There is two shorter (1.54 Å) and two longer (1.55 Å) P–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti4+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Mg2+, one Ti4+, and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti4+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Mg2+, one Ti4+, and one P5+ atom. Inmore » the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Mg2+ and two equivalent Ti4+ atoms.« less
