Abstract

A new metal hydra-cyanurate, K₂(C₃N₃O₃H), was synthesized by a slow evaporation method in aqueous solution. It possesses a short ultraviolet cutoff wavelength at 240 nm. First-principles calculations reveal that its birefringence (∼0.35@800nm) is two times larger than that of commercial calcite crystals. Therefore, K₂(C₃N₃O₃H) and metal cyanurates, are very promising ultraviolet birefringent materials in future optical devices.
