Abstract

Bi5Ti3FeO15 is Pb (Zr_0.50 Ti_0.48) O_3-derived structured and crystallizes in the monoclinic Cm 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 distorted TiO6 octahedra that share a cornercorner with one FeO6 octahedra and corners with four equivalent TiO6 octahedra. The corner-sharing octahedra tilt angles range from 14–17°. There are a spread of Ti–O bond distances ranging from 1.83–2.16 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 1.78–2.24 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 1.79–2.25 Å. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share a cornercorner with one TiO6 octahedra and corners with four equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 15–17°. There are a spread of Fe–O bond distances ranging from 1.93–2.12 Å. There are five inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Bi–O bond distances ranging from 2.22–2.98 Å. In the second Bi3+ site, Bi3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Bi–O bond distances ranging from 2.20–2.97 Å. In the third Bi3+ site, Bi3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Bi–O bond distances ranging from 2.19–2.96 Å. In the fourth Bi3+ site, Bi3+ is bonded in a 5-coordinate geometry to seven O2- atoms. There are a spread of Bi–O bond distances ranging from 2.21–3.01 Å. In the fifth Bi3+ site, Bi3+ is bonded in a 5-coordinate geometry to seven O2- atoms. There are a spread of Bi–O bond distances ranging from 2.21–3.02 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Ti4+, one Fe3+, and three equivalent Bi3+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Fe3+ and three Bi3+ atoms. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Ti4+ and two Bi3+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ti4+ and two equivalent Bi3+ atoms. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ti4+ and two equivalent Bi3+ atoms. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Ti4+, one Fe3+, and three equivalent Bi3+ atoms. In the seventh O2- site, O2- is bonded to four Bi3+ atoms to form a mixture of distorted edge and corner-sharing OBi4 tetrahedra. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one Ti4+ and three equivalent Bi3+ atoms. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one Ti4+ and three equivalent Bi3+ atoms. In the tenth O2- site, O2- is bonded in a 3-coordinate geometry to two Ti4+ and three equivalent Bi3+ atoms.
