3-Acetyl-1-(4-methylphenyl)thiourea
The asymmetric unit of the title compound, C(10)H(12)N(2)OS, contains two independent mol-ecules. In both mol-ecules, the conformations of the two N-H bonds are anti to each other. Furthermore, the conformations of the amide C=S bonds and the C=O bonds are anti to each other. The dihedral angles between the benzene ring and the side chain are 52.8 (1) and 68.0 (1)° in the two independent mol-ec...
متن کامل1-Acetyl-3-(4-chlorophenyl)-5-(4-fluorophenyl)-2-pyrazoline
In the title mol-ecule, C(17)H(14)ClFN(2)O, the mean plane of the pyrazoline ring makes dihedral angles of 18.19 (1) and 83.51 (4)° with the 4-chloro-benzene and 4-fluoro-benzene rings, respectively. The two benzene rings make a dihedral angle of 76.11 (2)°. Weak inter-molecular C-H⋯O hydrogen bonds help stabilize the crystal structure.
متن کاملCrystal structures of 2-acetyl-4-ethynylphenol and 2-acetyl-4-(3-hydroxy-3-methylbut-1-yn-1-yl)phenol
In the title compounds, C10H8O2, (I), and C13H14O3, (II), the 2-acetyl-4-ethynylphenol unit displays a planar geometry, which is stabilized by an intra-molecular O-H⋯O hydrogen bond. The crystal structure of (I) is constructed of infinite strands, along [101], of C-H⋯O=C hydrogen-bonded mol-ecules, which in turn are linked by C-H⋯π inter-actions. In the crystal of (II), which crystallized with ...
متن کامل3-Acetyl-4-hydroxyphenyl acrylate
In the title compound, C(12)H(12)O(4), the hydr-oxy O and the C and O atoms of the acetyl group are almost coplanar [maximum deviation = 0.0356 (1) Å] with the benzene ring. The dihedral angle between the benzene ring and the plane through the non-H atoms of the methacrylo-yloxy group is 86.1 (1)°. In the crystal structure, mol-ecules are linked by two C-H⋯O hydrogen bonds, forming dimers with ...
متن کامل3-Acetyl-2-methyl-4-phenylquinolin-1-ium chloride
An N-H⋯Cl hydrogen bond connects the ions in the title salt, C(18)H(16)NO(+)·Cl(-). The quinolin-1-ium residue is almost planar (r.m.s. deviation = 0.020 Å) but both the acetyl group [O-C-C-C torsion angle = 62.73 (17)°] and adjacent benzene ring [C-C-C-C torsion angle = -104.06 (14)°] are twisted out of this plane; the acetyl and benzene substituents are non-parallel [dihedral angle = 66.16 (7...
