Title: Materials Data on BaAl2(PO5)2 by Materials Project

Abstract

BaAl2(PO5)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Ba is bonded to twelve O atoms to form BaO12 cuboctahedra that share corners with eight equivalent AlO6 octahedra, corners with two equivalent PO4 tetrahedra, edges with two equivalent BaO12 cuboctahedra, edges with four equivalent PO4 tetrahedra, and faces with two equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 54–60°. There are a spread of Ba–O bond distances ranging from 2.88–3.34 Å. Al is bonded to six O atoms to form AlO6 octahedra that share corners with four equivalent BaO12 cuboctahedra, corners with four equivalent PO4 tetrahedra, an edgeedge with one AlO6 octahedra, and a faceface with one BaO12 cuboctahedra. There are a spread of Al–O bond distances ranging from 1.84–1.94 Å. P is bonded to four O atoms to form PO4 tetrahedra that share a cornercorner with one BaO12 cuboctahedra, corners with four equivalent AlO6 octahedra, and edges with two equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 44–49°. There are a spread of P–O bond distances ranging from 1.54–1.56 Å. There are five inequivalent O sites. In the first O site, O is bonded in a 2-coordinate geometry to one Ba, onemore » Al, and one P atom. In the second O site, O is bonded in a distorted bent 120 degrees geometry to one Ba, one Al, and one P atom. In the third O site, O is bonded in a 2-coordinate geometry to two equivalent Ba, one Al, and one P atom. In the fourth O site, O is bonded in a 2-coordinate geometry to one Ba, one Al, and one P atom. In the fifth O site, O is bonded in a 2-coordinate geometry to one Ba and two equivalent Al atoms.« less
