N-(4-Chlorobutanoyl)-N′-(2-fluorophenyl)thiourea

Abstract

In the title compound, C11H12ClFN2OS, the asymmetric unit consists of two indenpendent molecules. Both molecules maintain a trans–cis configuration of the positions of the butanoyl and fluorophenyl groups with respect to the thiono group across their C—N bonds and are stabilized by classical intramolecular N—H...O hydrogen bonds. In the crystal, intermolecular N—H...O, C—H...S and N—H...S hydrogen bonds link the molecules into infinite chains along the c axis.
