In the crystal structure of title compound, C(9)H(10)N(2)OS, there are two symmetry-independent mol-ecules, each having an intra-molecular N-H⋯O hydrogen bond generating an S(6) ring motif. The benzene rings and the virtually planar acetyl-thoiurea fragments [r.m.s. deviations = 0.0045 and 0.0341 Å] are oriented at dihedral angles of 50.71 (6) and 62.79 (6)° in the two mol-ecules. In the crysta...

As a follow-up to our effort establish reliable thermodynamic data for amino acids, the heat capacity and phase behavior are reported N-acetyl glycine amide (CAS RN: 2620-63-5), N-acetyl-L-alanine 15962-47-7), N-acetyl-L-valine 37933-88-3), N-acetyl-L-isoleucine 56711-06-9), N-acetyl-L-leucine 28529-34-2). Prior measurement, thermogravimetric analysis X-ray powder diffraction were performed det...

In the crystal structure of the title compound, C(10)H(12)N(2)OS, the conformation of the two N-H bonds are anti to each other. The amide C=O and the C=S are are also anti to each other. The N-H bond adjacent to the benzene ring is syn to the m-methyl groups. The dihedral angle between the benzene ring and the side chain [mean plane of atoms C-C(O)N-C-N; maximum deviation 0.029 (2) Å] is 14.30 ...

In the title compound, C(9)H(9)ClN(2)OS, the 3-chloro-phenyl and acetyl-thio-urea fragments are oriented at a dihedral angle of 62.68 (5)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. Mol-ecules are linked into dimers via a cyclic R(2) (2)(8) motif of N-H⋯S hydrogen bonds. These dimers are further connected through C-H⋯S inter-actions, completing an R(2) (2)(12) motif, ...
