Abstract

4-(3-Acetylphenyl)amino-2-methylidene-4-oxobutanoic acid (1) is synthesized by a ring opening reaction of itaconic anhydride with 3-aminoacetophenone and characterized by FT-IR, 1H NMR, UV-Vis, TGA, DTA, and single crystal X-ray diffraction. The crystal of 1 belongs to triclinic unit cell in the P-1 space group with the unit cell dimensions a = 4.9485(3), b = 5.3614(6), c = 22.457(2) à , α = 88.295(8), β = 89.379(7), γ = 84.495(7), and Z = 2 The crystal structure is solved by direct methods using single-crystal X-ray diffraction data collected at room temperature and refined by full-matrix least-squares procedures to a final R-value of 0.0467 for 1623 observed reflections. Intermolecular N\&sbnd;H.O and O\&sbnd;H.O hydrogen bonds links the molecules into chains along 010 direction. In addition the thermal stability of the 1 is determined by using DTA, TGA analysis, and wavelength absorption at λmax = 297 nm is determined by UV-Vis spectrophotometer.
