Materials Data on Li2Ti4Ni(PO5)4 by Materials Project
Li2Ti4Ni(PO5)4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with four PO4 tetrahedra, edges with two equivalent LiO6 octahedra, and faces with two equivalent TiO6 octahedra. The corner-sharing octahedral tilt angles are 60°. There are a spread of Li–O bond distances ranging from 2.12–2.21 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with four PO4 tetrahedra, edges with two equivalent LiO6 octahedra, and faces with two equivalent TiO6 octahedra. The corner-sharing octahedral tilt angles are 58°. There are a spread of Li–O bond distances ranging from 2.02–2.21 Å. There are two inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form distorted TiO6 octahedra that share corners with two LiO6 octahedra, corners with two equivalent TiO6 octahedra, corners with four PO4 tetrahedra, and a faceface with one NiO6 octahedra. The corner-sharing octahedra tilt angles range from 38–60°. There are a spread of Ti–O bond distances ranging from 1.74–2.23 Å. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form distorted TiO6 octahedra that share a cornercorner with one NiO6 octahedra, corners with two equivalent TiO6 octahedra, corners with four PO4 tetrahedra, and faces with two LiO6 octahedra. The corner-sharing octahedra tilt angles range from 38–51°. There are a spread of Ti–O bond distances ranging from 1.74–2.21 Å. Ni2+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with four PO4 tetrahedra, and faces with two equivalent TiO6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of Ni–O bond distances ranging from 2.03–2.12 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one NiO6 octahedra, corners with two LiO6 octahedra, and corners with four TiO6 octahedra. The corner-sharing octahedra tilt angles range from 30–53°. There are a spread of P–O bond distances ranging from 1.54–1.56 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one NiO6 octahedra, corners with two LiO6 octahedra, and corners with four TiO6 octahedra. The corner-sharing octahedra tilt angles range from 31–57°. There are a spread of P–O bond distances ranging from 1.54–1.56 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Ti4+, and one P5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to 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 bent 150 degrees geometry to one Ti4+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+ and two Ti4+ atoms. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two Ti4+ and one Ni2+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Ti4+, one Ni2+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two Li1+, one Ti4+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Ti4+, and one P5+ atom. In the tenth O2- site, O2- is bonded in a 3-coordinate geometry to one Ti4+, one Ni2+, and one P5+ atom.
