Nonlinear optical (NLO) crystals are critical for modern devices. In this study, two new hybrid metal halides, (C6H5N2)2CdCl4 (1) and (C6H5N2)2ZnCl4 (2), were synthesized by a mild solution method. 1 2 crystallize in different chiral space groups of P43212 P212121, respectively. Their crystal structures composed [MX4]2– (M = Cd, Zn) tetrahedrons (C6H5N2)+ cations with arrangements. They both have wide band gaps (3.98 3.83 eV). Attractively, exhibits SHG (second-harmonic generation) effect 1.2 × KDP, large birefringence (0.22@546 nm), high laser damage threshold (35 AgGaS2), can be grown up to centimeter level. Theoretical calculations show that these properties result from the ordered arrangement organic synergistic [MX4] tetrahedra, providing example develop high-performance NLO materials cation regulation.

Abstract Birefringent crystals are crucial in modulating the polarization state of light within contemporary technological applications. Organic molecules with π‐conjugated structure known to exhibit significant birefringence effect owing their unique electronic properties. This study demonstrates that 4, 5‐dichocyanimidazole can be used as a new crystal building block for birefringent crystals. Crystals C 5 N 4 H 2 ( DCI ) and ·H O DCI‐w obtained by evaporation at room temperature. It is worth noting birefringence. At 546 nm, experimental 0.417 calculated reaches 0.618. The significantly larger than those all commercial exceeds most metal‐free First‐principles calculations structural analysis show this remarkable mainly due strong anisotropy planar well‐organized arrangement groups. discovery opens up possibilities development high‐performance optical materials.

Inorganic selenites are promising candidates for nonlinear optical and birefringent crystals. However, that can effectively transmit in the UV region still relatively scarce. In this study, we successfully synthesized first Zn-based selenite with properties using a hydrothermal method by introducing Zn2+ La3+ ions, which cause blue shift compound's bandgap, into system. The compound crystallizes chiral space group P3112 presents unique three-dimensional structure composed of two-dimensional zinc layers bridged LaO10 polyhedra. Notably, possesses wide bandgap (5.0 eV), high birefringence (0.092 at 546 nm), excellent thermal stability (∼540 °C), broad transparency window (0.21-6 μm), apparent SHG efficiency (0.2 × KDP). Our work not only demonstrates great potential as crystals but also expands research scope materials.
