2-(3-Benzoyl-thio-ureido)-3-phenyl-propanoic acid

摘要

In the title compound, C17H16N2O3S, the phenyl-propanoic acid and the benzoyl moieties adopt a cis–trans conformation, respectively, with respect to the thiono S atom across the C—N bonds. An intra-molecular N—H?O hydrogen bond generates an S(6) ring. The crystal structure features carb-oxy-lic acid inversion dimers and pairwise N—H?S hydrogen bonds, which together generate [20-1] chains. Weak C—H?O hydrogen bonds are also observed.
