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 structures were determined by X-ray diffractometry.It belongs to the triclinic system,space group P1 with a = 7.7288(15),b = 11.168(2),c = 12.645(3) ,α = 107.02(3),β = 90.85(3),γ = 101.93(3)°,V = 1017.9(3) 3,Mr = 450.44,Z = 2,Dc = 1.470 g/cm3,λ = 1.54178 ,μ = 0.836 mm-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). 相似文献
