Abstract

Two new isostructural alkali metal hydroxyborates, AB₁₁O₁₆(OH)₂ (A = K and Cs), with two-dimensional (2D) interpenetrating [B₁₁O₁₈(OH)₂]_∞ layers have been successfully obtained. The calculated birefringences of KB₁₁O₁₆(OH)₂ and CsB₁₁O₁₆(OH)₂ are 0.104 and 0.100 at 546 nm, respectively. Moreover, KB₁₁O₁₆(OH)₂ exhibits a short DUV cutoff edge (195 nm).
