Materials Data on TiZn(BiO3)2 by Materials Project

Abstract

TiZn(BiO3)2 crystallizes in the tetragonal P4mm space group. The structure is three-dimensional. Ti4+ is bonded in a 5-coordinate geometry to five O2- atoms. There is one shorter (1.79 Å) and four longer (1.95 Å) Ti–O bond length. Zn2+ is bonded in a 5-coordinate geometry to five O2- atoms. There are one shorter (1.91 Å) and four longer (2.12 Å) Zn–O bond lengths. Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.32–2.89 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to one Ti4+, one Zn2+, and two equivalent Bi3+ atoms to form a mixture of distorted corner and edge-sharing OTiZnBi2 tetrahedra. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Zn2+ and four equivalent Bi3+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to one Ti4+ and four equivalent Bi3+ atoms.
