Abstract The title compound (C26H18N4O4) has been synthesized via a three-component reaction and it was characterized by means of IR and 1H NMR . Its crystal and molecular structure were determined by X-ray diffractometry . It belongs to the triclinic system, space group Pī with a = 7.7288 (15), b = 11.168(2), c = 12.645(3) Å, α = 107.02(3), β =90.85(3), γ = 101.93(3)°, V = 1017.9(3)Å3, Mr = 450.44, Z = 2, Dc = 1.470g/cm3, λ = 1.54178Å, μ= 0.836mm-1, F(000) =468, the final R=0.0488 and wR=0.1180. A total of 11903 reflections were collected, of which 3642 were independent(Rint=0.0377) and 3025 were observed with I>2σ(I).
