Materials Data on Ti(BiO3)2 by Materials Project

Abstract

Ti(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 (1.80 Å) and four longer (1.94 Å) Ti–O bond length. Bi4+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.25–2.93 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Ti4+ and two equivalent Bi4+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to four equivalent Bi4+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to one Ti4+ and four equivalent Bi4+ atoms.
