2-[(4-Chlorobenzoyl)amino]-3-(4-formylphenyl)prop-2-enoic acid (C17H12ClNO4) crystallizes in the orthorhombic space group Pbcn with unit cell parameters: a = 17.2460(13) Å, b = 9.6735(8) Å, c = 19.953(2) ?, α = β= γ = 90.00 o and Z=8. Direct methods were used to solve the crystal structure and refined by full matrix least squares proc?dures to final R value of 0.0675 for 1294 observed reflections. The crystal structure is stabilized by N?H⋅⋅⋅O, O?H⋅⋅⋅O and C?H⋅⋅⋅O hydrogen bonds. The dimer molecule is linked through a bifurcated(acceptor) hydrogen bond (N1-H1?O4,C17-H17?O4).
