Two independent mol-ecules comprise the asymmetric unit of the title compound, C(14)H(20)N(2)OS. 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 mol-ecule, the dihedral angles formed between the thio-urea and amide residues being 53.47 (17) and 55.81 (17)°. In the crystal, each mol-ecule ...
The title compound, C(13)H(12)N(2)O(2)S, crystallizes with two independent mol-ecules in the asymmetric unit. The two mol-ecules differ in the conformation of the thio-carbonyl and carbonyl groups, and show the typical geometric parameters of substituted thio-urea derivatives. The crystal structure is mainly stabilized by inter-molecular N-H⋯O hydrogen bonding.
The mol-ecule of the title compound, C(12)H(13)NO(2), adopts an essentially planar conformation (r.m.s. deviation = 0.057 Å). In the crystal, the mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds, generating chains along [201].
