N-(4-Chloro-butanoyl)-N′-(2-fluoro-phen-yl)thio-urea

Abstract

In the title compound, C 11H 12ClFN 2OS, the asymmetric unit consists of two indenpendent mol-ecules. Both mol-ecules maintain a trans-cis configuration of the positions of the butanoyl and fluoro-phenyl groups with respect to the thiono group across their C - N bonds and are stabilized by classical intra-molecular N - H⋯O hydrogen bonds. In the crystal, inter-molecular N - H⋯O, C - H⋯S and N - H⋯S hydrogen bonds link the mol-ecules into infinite chains along the c axis. Show more
