Bi4Ti3O12 is Pb (Zr_0.50 Ti_0.48) O_3-like structured and crystallizes in the orthorhombic Aea2 space group. The structure is three-dimensional. there are two inequivalent Ti4+ sites. In the first 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 1.78–2.36 Å. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles are 22°. There are a spread of Ti–O bond distances ranging from 1.85–2.11 Å. There are two 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 2.22–2.54 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 2.30–2.49 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ti4+ and two equivalent Bi3+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Ti4+ and two equivalent Bi3+ atoms. In the third O2- site, O2- is bonded in a distorted see-saw-like geometry to two Ti4+ and two equivalent Bi3+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Ti4+ and one Bi3+ atom. In the fifth O2- site, O2- is bonded to four equivalent Bi3+ atoms to form a mixture of edge and corner-sharing OBi4 tetrahedra. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ti4+ and one Bi3+ atom.
