Abstract

Bi9Ti6FeO27 crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. there are six inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded in a distorted see-saw-like geometry to four equivalent O2- atoms. All Ti–O bond lengths are 1.90 Å. In the second Ti4+ site, Ti4+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent O2- atoms. All Ti–O bond lengths are 1.90 Å. In the third Ti4+ site, Ti4+ is bonded to five O2- atoms to form distorted TiO5 square pyramids that share corners with four equivalent BiO6 octahedra. The corner-sharing octahedral tilt angles are 17°. There is one shorter (1.70 Å) and four longer (1.98 Å) Ti–O bond length. In the fourth Ti4+ site, Ti4+ is bonded to five O2- atoms to form TiO5 square pyramids that share corners with four equivalent FeO5 square pyramids. There is one shorter (1.86 Å) and four longer (1.96 Å) Ti–O bond length. In the fifth Ti4+ site, Ti4+ is bonded to six O2- atoms to form corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles are 9°. There are a spread of Ti–O bond distances ranging from 1.84–2.10 Å.
