Here we reported the crystal structure of title molecule. The crystal is monoclinic, belonging to space group Pl with unit cell parameter a=0.9134(2) nm,b=0. 9567(4) nm,c=1.2647(3)nm,a=73.88(3)°,β-70.93(2)°,γ=64.05(4)°,V=0.9273 nm ̄3,Dx=1.36g/cm ̄3,μ=1.99 cm(-1), F(000)=396 for 1818 reflections.R=0. 063. Molecular structure has been discussed. There are three different planes in the molecule, in each of which a conjugated system was formed. The intra-moleucle hydrogen bond between N and H atom has been found.
