Abstract
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) Å, α = β = γ = 90.00 and Z=8. Direct methods were used to solve the crystal structure and refined by full matrix least squares procédures to a 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).
