Hydrothermal synthesis of new mixed-oxoanion materials: Rare earth iodate sulfates Sm(IO3)(SO4) and Ln2(IO3)3(SO4)OH·3H2O (Ln = Sm, Eu, Dy)

MIO3F (M = Co and Ni): Magnetic Iodate Fluorides with Zigzag Chains

“…For example, introducing a new F – anion to the iodate ion group has been rapidly studied to increase the electronegativity and polarizability as well as to be the secondary basic building units (BBUs) for the enhancement of the band gap and second harmonic generation (SHG) response. − After screening the literature, it is found that about 90% fluorine-containing metal iodates or simply called metal iodate fluorides have been reported in the past five years. For all metal iodate fluorides, they could be divided into two categories (Figure ): (i), the fluorine anion is bonded to the iodine cation (or called fluoroiodates), forming the IO 3 F group, , IO 2 F 2 group, ,− IOF 4 group, , IO 2 F 4 group, and I 2 O 5 F 2 dimer group , in the crystal structures; (ii), the fluorine anion is only bonded to the metal cation, forming the IO 3 group, − ,− IO 4 group, and IO 5 group . Thus, combining the fluorine anion F – and iodate anion groups [IO x F y ] n − is promising to design and build various new compounds with rich crystal structures and functional properties.…”
