| Abstract: | 1-Phenyl-1,3-butandione benzidine diketoimine 2a (C32H28N2O2, Mr = 472.56) was synthesized in high yield by the reaction of 1-phenyl-1,3-butandione with benzidine in absolute ethanol,and determined by X-ray structure analysis. It crystallizes in the orthorhombic system, space group P21/c with a = 7.9839(16), b = 12.910(3), c = 12.358(3) (A), α = 90.00, β = 93.71(3), γ = 90.00°, V = 1271.1(4) (A)3, Z = 2, Dc = 1.235 g/cm3, μ = 0.077 mm－1, F(000) = 500, the final R = 0.0717 and wR = 0.1187. It presents a linear centrosymmetric framework constituted by a linkage of benzidine as a bridge and two terminal 1-phenyl-1,3-butanedione moieties. |
