RbB7O10(OH)2 and NaB11O16(OH)2: Alkali Metal Hydroxyborates with Two-dimensional Layered Structures and Large Birefringence

Hydroxyborates have attracted much research attention due to their rich structural and outstanding optical properties. Herein, two new alkali metal hydroxyborates, RbB7O10(OH)2 and NaB11O16(OH)2, with two-dimensional (2D) layered structures have...
