Iodate nitrates are
mixed anion compounds that contain both
iodate and
nitrate
anions .
Giant birefringence
Iodate nitrates can have high
birefringence . The scandium salt has a
giant birefringence of 0.348 at 546 nm. When discovered in 2021 it was a record high birefringence for
oxyanion compounds, but it was exceeded by CeF2 (SO4 ) just a month later with a value of 0.361
[1] and sodium hydrogen squarate hydrate, NaHC4 O4 ·H2 O with a value of 0.52 at 1064 nm.
[2] All of these are beaten by
hexagonal boron nitride (h-BN) with birefringence of 0.7 in visible light.
