The structure of caesium terbium(IV) pentafluoride has been determined
by single-crystal X-ray methods. CsTbF5 has a layered structure. The
layers, which stack along the [100] direction, are built from edge- an
d corner-sharing (TbF8)(4-) dodecahedra and are held together by 11-co
ordinate Cs+ ions. CsTbF5 is closely related to TlZrF5.
