Materials Data on Ti3Zn2O8 by Materials Project
Zn2Ti3O8 crystallizes in the cubic P4_332 space group. The structure is three-dimensional. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six equivalent ZnO4 tetrahedra and edges with four equivalent TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 1.88–2.08 Å. Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with nine equivalent TiO6 octahedra. The corner-sharing octahedra tilt angles range from 53–58°. There is three shorter (1.98 Å) and one longer (1.99 Å) Zn–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Ti4+ and one Zn2+ atom to form distorted corner-sharing OTi3Zn trigonal pyramids. In the second O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Ti4+ and one Zn2+ atom.
