摘要
The compound of 3,5-diazido-1,2,4-triazole was synthesized by the reaction of 2,5,2＇,5＇-tetrachloro-1,1＇-azo-1,3,4-triazole with sodium azide at 50 ℃.Its crystal structure was determined by single-crystal X-ray diffraction.It crystallizes in monoclinic,space group Cc with a=1.212 4（2） nm,b=2.342 4（5） nm,c=0.804 74（16） nm,β=125.56（3）°,V=1.859 3（6） nm3,Z=4,C2HN9,Mr=151.04,Dc=1.62 g/cm3,F（000）=912 and μ（MoKa）=0.129 mm-1,the final R=0.039 7 and wR=0.087 4.X-ray analysis indicates a stronger intermolecular hydrogen bonding,leading to the formation of a trimmer,containing a nine-membered cyclic ring with graph-set R33（9） in the compound.
