Abstract

The crystal structure of N-isopropylanthranilic acid trimer was characterized by a single-crystal X-ray diffraction method to study the conformation of oligo(o-benzamide). The compound crystallized in a triclinic space group, P1, with a = 7.720(4)Å, b = 9.006(4)Å, c = 20.131(9)Å, α = 92.459(7)°, β = 95.299(7)°, γ = 91.099(7)°, V = 1391.9(11)Å³, and Z = 2. In the crystal structure, one of the amide linkages adopts a cis conformation, while the other adopts a trans conformation.
