Rerefinement of K2[TiF6]

Crystals of dipotassium hexa­fluoro­titanate(IV), K₂TiF₆], were grown from aqueous solution. The crystal structure was refined with anisotropic displacement parameters. Ti⁴⁺ is octahedrally coordinated by F^? (point group m), and K⁺ is 12‐coordinate (point group 3m). The dispersion of birefringence is presented.
