Birefringent materials, capable of manipulating light polarization, are pivotal in advanced optical technologies. Traditionally, the development such materials has predominantly focused on purely inorganic compounds, which often exhibit limited birefringence. Herein, we present a new 3-pyridinesulfonate birefringent crystal, Ca(3-C5H4NSO3)2·4H2O, synthesized via hydrogen-bonded regulation strategy designed to enhance coplanarity [3-pySO3] groups. As expected, Ca(3-C5H4NSO3)2·4H2O demonstrates notably large birefringence 0.286@532 nm, exceeding that most commercially available crystals. Furthermore, this compound outstanding environmental stability and short ultraviolet (UV) absorption cutoff edge at 257 accompanied by wide band gap 4.4 eV. A combination structural analysis theoretical calculations unraveled crucial role hydrogen bonds optimizing arrangement rings. This effectively induces high degree facilitates formation quasi-2D layered structure, thereby contributing exceptional anisotropy Ca(3-C5H4NSO3)2·4H2O. These findings highlight as promising UV crystal underscore efficacy bond engineering for designing with enhanced properties.

Abstract Birefringent materials play a crucial role in advanced applications such as nonlinear optics, high‐density data storage, and display technologies. Three birefringent compounds, P 4 S 3 ( 1 ), 5 2 7 are studied, all exhibiting broad transmission the range of ≈0.38–14 µm, with remarkable birefringence values 0.178, 0.173, 0.194 @546 nm, respectively, surpassing that commercial α ‐BaB O (0.124 nm). The relationships between their topological atomic bonding properties performance established by high‐resolution experimental charge density. unusual phenomenon considerable differences single molecule polarizability anisotropy among – , despite similar crystal birefringence, can be attributed to 3D aromaticity packing effects, which induce enhanced electron delocalization directional noncovalent π–π interactions, unprecedently field materials. This work provides valuable insights for design new leveraging effects favorable density characteristics.
