K₆(IO₆H₄)(HI₂O₆)(HIO₃)₂(IO₃)₄·2H₂O: A Case of Iodate with Coexisting [I⁵⁺O₃] and [I⁷⁺O₆] Units

Designing a Strong Second-Harmonic Generation Polar Iodate by the Structure-Directing Properties of the “Tumbler-like” [Zn(IO3)(I2O5(OH))] Polyanions

“…For IO 3 pyramids, the I–O distances range from 1.791(9) to 1.861(10) Å, while for IO 4 units, they possess a wider I–O distance range from 1.798(9) to 2.364(13) Å. Clearly, all these I–O bond distances are consistent with those in other iodates, i.e., K 6 (IO 6 H 4 )­(HI 2 O 6 )­(HIO 3 ) 2 (IO 3 ) 4 ·2H 2 O, Ba 2 [MoO 3 F­(IO 3 )]­(MoO 3 F 2 ), and Ba 2 [MoO 3 (OH)­(IO 3 ) 2 ]­IO 3 . The bond valence sum (BVS) calculations show that the BVSs for K + , Zn 2+ , I 5+ , and O 2– ions are 0.85–1.09, 1.95, 4.86–5.15, and 1.75–2.29, respectively (Table S2), which are all consistent with their expected oxidation states.…”

Na7(SeO4)3(IO3) and K2(SeO4)[IO2(OH)]: two new iodate-selenates with short-wave UV cutoff edge and large birefringence

“…3, we enumerate the absorption edges of the title compounds and some other reported iodates. 29,43–59 Apparently, only about 30% of these compounds have absorption edge values that reach the short-wave UV region (<300 nm). The band gaps of the two title compounds were successfully widened by introducing the [SeO 4 ] group with wide transmittance into an iodate system.…”

Synthesis and characterization of a new isoxazolone-based nonlinear optical crystal: MPMOI

“…Nonlinear optical (NLO) crystals have attracted more and more attention because of their promising applications in many technology fields, such as THz imaging and spectroscopy, optical data storage, and telecommunications. 1–10 Inorganic NLO crystals ( e.g. , ZnGeP 2 , ZnTe, and LiNbO 3 ) for a long time have been hotspot materials due to their excellent linear and nonlinear optical and mechanical properties.…”
