N-(Biphenyl-4-ylcarbonyl)-N′-(2-pyridylmethyl)thiourea

Abstract

In the title compound, C20H17N3OS, the dihedral angle between the benzene rings of the biphenyl fragment is 36.84 (9)°. The trans-cis geometry of the thio-urea unit is stabilized by intra-molecular N - H⋯O and N - H⋯N hydrogen bonds between the H atom of the cis thio-amide and the carbonyl O and pyridine N atoms, respectively. In the crystal structure, inter-molecular N - H⋯S hydrogen bonds form centrosymmetric dimers extending along the b axis. Show more
