A zinc(Ⅱ) complex [(5-(4-nitrophenyl)tetrazolato)2Zn]n was obtained by the hydrothermal treatment of ZnBr2 and NaN3 with 4-nitrobenzonitril in water at 120 ℃ in Pyrex tube. The crystal belongs to orthorhombic system with space group Pbcn, and a=1.040 7(5) nm, b=1.382 1(7) nm, c=2.435 1(13) nm, V=3.503(3) nm3, Z=8. This complex is a good blue fluorescent material in solid state at room temperature. CCDC: 684226.
