Spectroscopic Studies and Structure of 4-(3-Benzoylthioureido)benzoic Acid

Abstract

4-(3-Benzoylthioureido)benzoic acid has been synthesized from the reaction of 4-aminobenzoic acid with benzoyl isothiocyanate. The title compound has been characterized by elemental analysis, MS, FT-IR, (1)H-NMR, (13)C-NMR and UV-Visible techniques. The structure of the compound has also been examined crystallographically. The title compound crystallizes in the triclinic space group P-1 with a = 3.969(1), b = 13.039(1), c = 13.504(1) angstrom, alpha = 96.50(1)degrees, beta = 92.25(1)degrees, gamma = 94.94(1), V = 691.0(1) angstrom(3) and D(x) = 1.444 g cm(-3), respectively. The crystal structure has been solved by direct methods and refined by full-matrix least squares and found R (1) = 0.031 and wR (2) = 0.081 for 2909 observed reflections [I > 2 sigma(I)].
