'''Hafnium tetrafluoride''' is the ] with the formula HfF<sub>4</sub>. It is a white solid. It adopts the same structure as ], with 8-coordinate Hf(IV) centers. |
|
|
|
|
|
Hafnium tetrafluoride forms a trihydrate, which has a polymeric structure consisting of octahedral Hf center, described as {{chem2|(μ\sF)2}}<sub>n</sub>(H<sub>2</sub>O)<sub>n</sub> and one ]. In a rare case where the chemistry of Hf and Zr differ, the trihydrate of zirconium(IV) fluoride has a molecular structure {{chem2|(μ\sF)22}}, without the lattice water.<ref>{{Greenwood&Earnshaw2nd|page=965}}</ref> |
