The title compound (S)-N-(2-oxoazepan-3-yl)biphenyl-4-carboxamide (C₁₉H₂₀N₂O₂, M_r=308.37) was synthesized by the reaction of (S)-α-amino-Σ-caprolactam with 4-phenyl-benzoyl chloride. Its chemical structure was determined by ¹H NMR, ¹³C NMR, H RMS and X-ray single-crystal diffraction. The crystal belongs to the triclinic system, space group P1 with a=8.2650(17), b=13.774(3), c=15.109(3)Å, β=90.20(3)°, V=1645.6(6)Å³, Z=4, D_c=1.245 g/cm³, μ=0.081 mm^-1, F(000)=656, R=0.0756 and wR=0.1491 for 5964 observed reflections with I>2σ(I). The title compound was also used to prepare polyamide.
