The introduction of lone‐pair electrons in microscopic structures is beneficial to the enhancement of optical anisotropy in crystals. Guided by this molecular design strategy, a new compound, BaSn 2 (PO 4 ) 2 , the first alkaline‐earth metal phosphate, with very large optical birefringence, was synthesized. This work may have significant implications for the discovery of key materials for modulating the polarization of light in the optical communication and laser industries.
