Crystal structure of (E)-4-{1-[2-(carbamothioyl)hydrazin-1-ylidene]ethyl}phenyl 4-methylbenzoate
The asymmetric unit of the title compound, C17H17N3O2S, consists of two independent mol-ecules, A and B, with different conformations: in mol-ecule A, the dihedral angles between the central benzene ring and the pendant tolyl and carbamo-thio-ylhydrazono groups are 71.12 (9) and 5.95 (8)°, respectively. The corresponding angles in mol-ecule B are 50.56 (12) and 26.43 (11)°, respectively. Both m...
متن کاملCrystal structure of (E)-2-[4-(4-hydroxyphenyl)butan-2-ylidene]hydrazine-1-carbothioamide
The title compound, C11H15N3OS, is a thio-semicarbazone derivative of the raspberry ketone rheosmin [systematic name: 4-(4-hy-droxy-phen-yl)butane-2-one]. The mol-ecule deviates from planarity, with the bridging C-C-C=N torsion angle equal to -101.3 (2)°. The maximum deviation from the mean plane of the non-H atoms of the thio-semicarbazone fragment [C=N-N-C(= S)-N] is 0.085 (5) Å for the Schif...
متن کاملCrystal structure of 1-methyl-2-[(E)-2-(4-methylphenyl)ethenyl]-4-nitro-1H-imidazole
In the title mol-ecule, C13H13N3O2, the planes of the benzene and imidazole rings form a dihedral angle of 7.72 (5)°. In the crystal, mol-ecules are linked by weak C-H⋯N and C-H⋯O hydrogen bonds, forming layers parallel to (100). A weak C-H⋯π inter-action connects these layers into a three-dimensional network. A π-π stacking inter-action, with a centroid-centroid distance of 3.5373 (9) Å, is al...
متن کاملSynthesis, Spectral Characterization and Analgesic Activity of 2-Methylthio-1, 4-Dihydropyrimidines
A series of 2-methylthio-1,4-dihydropyrimidine derivatives (II) were synthesized in good yields by alkylation of 1,2,3,4-tetrahydropyrimidines (I) with methyl iodide in the presence of pyridine. Their structures were confirmed by elemental analysis, IR and 1H NMR spectra. The compounds were tested for analgesic activity by acetic acid induced writhing method. Compounds IIh, IIe, IIk and IIl sho...
متن کاملCrystal structure of (E)-N-{2-[2-(4-methylbenzylidene)hydrazin-1-yl]-2-oxoethyl}-p-toluenesulfonamide
The title acyl-hydrazone derivative, C17H19N3O3S, containing an amino acid moiety and electron-donating substituents attached to both the phenyl rings, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The mol-ecules are bent at the S atom, with C-SO2-NH-CH2 torsion angles of -67.3 (2) and 67.7 (3)° in mol-ecules A and B, respectively. Further, the dihedral angles b...
