Dibarium dititanium difluoride dioxide heptaoxidodisilicate, Ba(2)Ti(2)Si(2)O(9)F(2), is a new edge-sharing titanate with a unique titanium silicate framework. All atoms in the structure are in general positions. Titanium oxyfluoride octahedra combine with silicon tetrahedra to form a double stacked chain, which is the base unit of the layered framework. The Ba atoms lie in channels that extend along the a axis.
