A new phase of Ba3(C3N3O3)2 (I) was grown from RbCNO and BaCl2 by a solid state cyclo-trimerization reaction. It crystallizes in space group R3̅ with the cell parameters of a = 7.0934(2) Å and c = 20.1130(9) Å, featuring a layered structure stacked from the ∞2[Ba(C3N3O3)2]2– double layers along the c direction. I exhibits wide ultraviolet transparency and large optical anisotropy of Δn = 0.32 at 800 nm, two times than that of the benchmark birefringent crystal calcite. The discovery of I shows that replacement of calcite is conceivable and opens the novel pathway for designing novel ultraviolet birefringent crystals in metal cyanurates.

Ba 3（C 3 N 3 O 3）2：含平行π共轭基团的氰尿酸钡的新相作为方解石的双折射材料替代物
通过固态环三聚反应，由RbCNO和BaCl 2生成了Ba 3（C 3 N 3 O 3）2（I）的新相。该晶体的空间群[R 3与小区参数一个= 7.0934（2）埃，c ^ = 20.1130（9）埃，具有从所述层叠的层状结构∞ 2 [巴（C 3 Ñ 3 ö 3）2 ] 2 –沿c方向的双层。一世在800 nm处具有宽的紫外线透明性和Δn = 0.32的大光学各向异性，是基准双折射晶体方解石的两倍。I的发现表明方解石的替代是可以想到的，并为设计氰尿酸金属中的新型紫外线双折射晶体开辟了新途径。
