Abstract

Two independent mol­ecules comprise the asymmetric unit of the title compound, C14H20N2OS. These differ in the relative orientations of the pentyl chains [C—C—C—C torsion angles = −176.7 (3) and 176.4 (3)°]. Significant twists are evident in each mol­ecule, the dihedral angles formed between the thio­urea and amide residues being 53.47 (17) and 55.81 (17)°. In the crystal, each mol­ecule self-associates via a centrosymmetric eight-membered {⋯HNC=S}2 synthon, and these are connected into a supra­molecular chain along [110] via C—H⋯O contacts. Disorder is noted for one of the independent mol­ecules in that two orientations (50:50) were resolved for its benzene ring.
