Materials Data on Ti2Zn3O7 by Materials Project
Ti2Zn3O7 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. Ti4+ is bonded to six O2- atoms to form corner-sharing TiO6 octahedra. The corner-sharing octahedra tilt angles range from 38–42°. There are a spread of Ti–O bond distances ranging from 1.96–2.02 Å. There are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Zn–O bond distances ranging from 2.05–2.20 Å. In the second Zn2+ site, Zn2+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Zn–O bond distances ranging from 2.00–2.68 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to one Ti4+ and three equivalent Zn2+ atoms to form corner-sharing OTiZn3 tetrahedra. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ti4+ and two equivalent Zn2+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ti4+ and two Zn2+ atoms. In the fourth O2- site, O2- is bonded to two equivalent Ti4+ and two equivalent Zn2+ atoms to form distorted corner-sharing OTi2Zn2 tetrahedra.
