Materials Data on TiZnAsO5 by Materials Project
TiZnAsO5 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Ti3+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with four equivalent AsO4 tetrahedra and edges with two equivalent TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 1.92–2.11 Å. Zn2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Zn–O bond distances ranging from 1.89–2.59 Å. As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with four equivalent TiO6 octahedra. The corner-sharing octahedra tilt angles range from 42–58°. There are a spread of As–O bond distances ranging from 1.73–1.77 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted T-shaped geometry to two equivalent Ti3+ and one As5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one As5+ atom. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Ti3+, one Zn2+, and one As5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Ti3+, one Zn2+, and one As5+ atom. In the fifth O2- site, O2- is bonded in a trigonal non-coplanar geometry to two equivalent Ti3+ and one Zn2+ atom.
