Materials Data on Ti3(BiO3)4 by Materials Project
Bi4Ti3O12 is Pb (Zr_0.50 Ti_0.48) O_3-like structured and crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are three inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form corner-sharing TiO6 octahedra. The corner-sharing octahedra tilt angles range from 22–32°. There are a spread of Ti–O bond distances ranging from 1.85–2.12 Å. In the second Ti4+ site, Ti4+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ti–O bond distances ranging from 1.79–2.34 Å. In the third Ti4+ site, Ti4+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ti–O bond distances ranging from 1.76–2.52 Å. There are four inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Bi–O bond distances ranging from 2.24–2.58 Å. In the second Bi3+ site, Bi3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Bi–O bond distances ranging from 2.23–2.71 Å. In the third Bi3+ site, Bi3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Bi–O bond distances ranging from 2.31–2.53 Å. In the fourth Bi3+ site, Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.31–2.78 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded to four Bi3+ atoms to form a mixture of edge and corner-sharing OBi4 tetrahedra. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two Ti4+ and two equivalent Bi3+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ti4+ and two equivalent Bi3+ atoms. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Ti4+ and two equivalent Bi3+ atoms. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ti4+ and two equivalent Bi3+ atoms. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Ti4+ and two Bi3+ atoms. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ti4+ and one Bi3+ atom. In the eighth O2- site, O2- is bonded to four Bi3+ atoms to form a mixture of edge and corner-sharing OBi4 tetrahedra. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Ti4+ and two equivalent Bi3+ atoms. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to one Ti4+ and two equivalent Bi3+ atoms. In the eleventh O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Ti4+ and one Bi3+ atom. In the twelfth O2- site, O2- is bonded in a distorted see-saw-like geometry to two Ti4+ and two equivalent Bi3+ atoms.
