Stereochemically active lone pair-induced large optical anisotropy in a novel infrared birefringent crystal Ba <sub>2</sub> La <sub>2</sub> Sb <sub>4</sub> S <sub>10</sub> (S <sub>2</sub> )
The first compound Ba 2 La 2 Sb 4 S 10 (S 2 ) in the Ba–La–Sb–S system was successfully synthesized via a vacuum high-temperature solution method, exhibiting large birefringence (0.53 at 1064 nm) induced by the stereochemically active lone pair effect.
