In the title compound, C(12)H(15)N(3)O(3)S, there is an intra-molecular N-H⋯O hydrogen bond. The crystal structure is stabilized by inter-molecular N-H⋯O, N-H⋯S and C-H⋯S hydrogen bonds, forming a two-dimensional network parallel to the ac plane.

n, n΄-3, 4-di(methylamino)-1, 2, 5-oxadiazole (1f) was prepared by dehydration of n, n΄-3, 4-di(methylamino)glyoxime (2f) in aqueous potassium hydroxid at 170-180 ˚c. under similar conditions n, n΄-3, 4-di(benzylamino)-1, 2, 5-oxadiazole (1c) and n, n΄-3, 4-di(isopropylamino)-1, 2, 5-oxadiazole (1e) were not obtained, but, n, n΄-3, 4-di(ethylamino)-1, 2, 5-oxadiazole (1g) was appeared with smal...

The title compound, C(10)H(11)ClN(2)OS, adopts a cis-trans configuration with respect to the position of the phenyl and 3-chloro-propionyl groups relative to the thiono group across the C-N bonds. The benzene ring is perpendicular to the propionyl thio-urea fragment with a dihedral angle of 82.62 (10)°. An intra-molecular N-H⋯O inter-action occurs. The crystal structure is stabilized by inter-m...
