description: Bi6Ti3WO18 is Pb (Zr_0.50 Ti_0.48) O_3-derived structured and crystallizes in the triclinic P1 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 corners with four equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 23–29°. There are a spread of Ti–O bond distances ranging from 1.81–2.25 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 1.79–2.38 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 1.78–2.48 Å. W6+ is bonded to six O2- atoms to form WO6 octahedra that share corners with four equivalent TiO6 octahedra. The corner-sharing octahedra tilt angles range from 23–29°. There are a spread of W–O bond distances ranging from 1.88–2.10 Å. There are six inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 6-coordinate geometry to six O2- atoms.
