摘要: Dibarium dititanium difluoride dioxide heptaoxidodisilicate, Ba2Ti2Si2O9F2, is a new edge-sharing titanate with unique titanium silicate framework. All atoms in the structure are general positions. Titanium oxyfluoride octahedra combine silicon tetrahedra to form double stacked chain, which base unit of layered The Ba lie channels that extend along axis.
