The title compound,1|(4|Chlorophenyl)|3|(4|Nitrophenyl)|1|Triazene, crystallized in the orthorhombic system, space group Pbca, with a=13.793(2), b=10.843(2), c=16.851(2), V=2520.2(7) 3 D c =1.458g/cm 3, Z =8, C 12 H 9ClN 4O 2, M r=276.68, μ (Mo Kα )=0.306mm -1 , F (000)=1136. The structure was refined to R=0.0372, wR =0.0786 for 1216 reflections ( I>2σ(I )). The title molecule has trans geometry about the central triazenyl linkage. The dihedral angle between the two phenyl rings is only 5.8(2)°. They are also nearly coplanar with the triazenyl. The screw related molecules are connected by hydrogen bond N(3)-H…O(2) and form the zigzag chains. The polar molecular chains are antiparallelly stacked through π…π interactions. The interstack interaction is mainly van der Waals force.
