AB 11 O 16 (OH) 2 (A = K and Cs): interpenetrating 2D layers with large birefringence

Two new isostructural alkali metal hydroxyborates, AB 11 O 16 (OH) 2 (A = K and Cs), with two-dimensional (2D) interpenetrating [B 11 O 18 (OH) 2 ] ∞ layers have been successfully obtained. The calculated birefringences of KB 11 O 16 (OH) 2 and CsB 11 O 16 (OH) 2 are 0.104 and 0.100 at 546 nm, respe...

Description
Summary:Two new isostructural alkali metal hydroxyborates, AB 11 O 16 (OH) 2 (A = K and Cs), with two-dimensional (2D) interpenetrating [B 11 O 18 (OH) 2 ] ∞ layers have been successfully obtained. The calculated birefringences of KB 11 O 16 (OH) 2 and CsB 11 O 16 (OH) 2 are 0.104 and 0.100 at 546 nm, respectively. Moreover, KB 11 O 16 (OH) 2 exhibits a short DUV cutoff edge (195 nm).
