N-(Biphenyl-4-carbonyl)-N′-(4-chlorophenyl)thiourea

Abstract

In the title compound, C20H15ClN2OS, the benzene rings of the biphenyl group are at an angle of 44.23 (12)°. The C4N2OS central thio-urea fragment makes dihedral angles with the benzene carbonyl and chloro-benzene rings of 55.96 (9) and 64.09 (9)°, respectively. The trans-cis geometry of the thio-urea group is stabilized by the intra-molecular hydrogen bond between the carbonyl O atom and the H atom of the cis-thio-amide. In the crystal structure, mol-ecules are linked by N - H⋯S and N - H⋯O inter-molecular hydrogen bonds to form one-dimensional chains along the c axis. C - H⋯π inter-actions also contribute to the stability of the mol-ecule. Show more
