Structures and Nonlinear Optical Properties of Two Acentric Borates with Cubic Cage-like Frameworks
Two new acentric borates, Li<sub>2</sub>Sr<sub>0.5</sub>[B<sub>3</sub>(BO<sub>3</sub>)<sub>4</sub>] (<b>1</b>) and Na<sub>4</sub>[Al<sub>3</sub>(BO<sub>3</sub>)<sub>4</sub>]·Cl (<b>2</b>), with cage-like frameworks constructed by BO<sub>3</sub> and TO<sub>4</sub> (T = B (<b>1</b>), Al (<b>2</b>)) units, were hydrothermally synthesized. The 3D anionic frameworks of <b>1</b> and <b>2</b> are built by two types of isostructural B-O and Al-B-O cages, respectively, and are further interpenetrated by polyhedral cubic unit (<i>pcu</i>) cationic frameworks. Both compounds not only feature novel interpenetrating <i>pcu</i> anionic and cationic frameworks, which are rarely observed in borate structural chemistry, but also exhibit moderate second harmonic generation (SHG) responses and a short cutoff edge, indicating their potential as deep ultraviolet nonlinear optical (NLO) crystals.
