New vanadium(IV) and titanium(IV) oxyfluoro­tellurates(IV): V₂Te₂O₇F₂ and TiTeO₃F₂

The crystal structures of two new phases, TiTeO₃F₂ and V₂Te₂O₇F₂, extend to Ti^IV and V^IV cations the description of the structural features established for some oxyfluoro­tellurates(IV) of trivalent cations, belonging to the three MTeO₃F [M = (Fe, Cr, Ga), Sc or In] types recently characterized.
