WebFeb 15, 2024 · A new polar hafnium iodate, CsHfF 4 (IO 3), was successfully designed and synthesized by integrating fluorinated hafnium–oxygen polyhedra (HfF 6 O 2) and IO 3 – anionic functional groups. Owing to the weak electronic effect of Hf 4+ and the bond-network-induced out-of-center distortion of the HfF 6 O 2 dodecahedra, CsHfF 4 (IO 3) …
