In the title compound, C(19)H(13)Br(2)NO, the dihedral angle between the rings of the biphenyl group is 53.59 (14)°. The ring of the benzamide group is inclined to the phenyl rings of the biphenyl group by 23.87 (15) and 75.89 (15)°. There are no significant inter-molecular inter-actions in the crystal structure.
In the title compound, C(13)H(10)BrNO, the benzene ring planes are inclined at an angle of 48.85 (17)°, resulting in a nonplanar mol-ecule. A characteristic of aromatic Schiff bases with N-aryl substituents is that the terminal phenyl rings are twisted relative to the HC=N plane. In this case, the HC=N unit makes dihedral angles of 11.1 (4) and 38.5 (3)°… (More)
Acetophenone thiosemicarbazone (APTSC) was synthesized. Solubility of APTSC was determined in ethanol and methanol at different temperatures. Single crystals were grown from ethanol by slow evaporation at room temperature. The grown crystal was subjected to FTIR, Laser-Raman and (1)H NMR spectral analyses to confirm the synthesized compound. Thermal… (More)
The title compound, C(25)H(31)NO(2).H(2)O, has the outer two six-membered rings in chair conformations, while the central ring is in an 8beta,9alpha-half-chair conformation. The five-membered ring adopts a 13,14-half-chair conformation. The pyridylmethylene moiety has an E configuration with respect to the carbonyl group at position 17. The structure is… (More)
In the title compound, C11H10N3OS(+)·Cl(-)·2H2O, the organic cation exhibits a dihedral angle of 21.26 (8)° between the mean planes of the pyridine and thio-phene rings, and dihedral angles of 15.11 (9) and 6.49 (9)° between the mean planes of the hydrazide moiety and the pyridine and thio-phene rings, respectively. In the crystal, the organic cation, the… (More)
The title compound, C(32)H(45)N(2)O(+).Br(-).0.5H(2)O, has the outer two six-membered rings in chair conformations, while the central ring is in an 8beta,9alpha-half-chair conformation. The five-membered ring of the steroid nucleus adopts a slightly deformed 14alpha-envelope conformation. The pyridylmethylene moiety has an E configuration with respect to… (More)
In the title compound, C(23)H(21)N(3)O, the dihedral angles formed by the mean plane of the triazole ring [maximum deviation = 0.007 (1) Å] and the three phenyl rings are 51.13 (8), 52.84 (8) and 47.04 (8)°. In the crystal, mol-ecules are linked by weak C-H⋯N inter-actions, forming infinite chains propagating along the b-axis direction.
In he title compound, C(16)H(13)Br(4)N, the carbazole skeleton is nearly planar [maximum deviation = 0.026 (4) Å] and makes a dihedral angle of 73.8 (4)° with the butyl chain. The butyl chain adopts a trans conformation. In the crystal, mol-ecules are linked by π-π stacking inter-actions [centroid-centroid distance = 3.559 (2) Å].
In the title mol-ecule, C22H18O, the o-tolyl ring is connected through a conjugated double bond. The mol-ecule adopts an E conformation and the C-C=C-C torsion angle is 178.77 (13)°. The overall conformation may be described by the values of dihedral angles between the different planes. The terminal rings are twisted by an angle of 54.75 (8)°, while the… (More)
In the title compound, C(25)H(17)NO(4), the indolizine fused naphthaquinone unit is approximately planar [r.m.s deviation = 0.0678 Å] and makes a dihedral angle of 57.82 (5)° with the benzene ring of the meth-oxy-benzene group. The naphtho-quinone O atoms deviate, in the same sense, from the mean plane of the fused six-membered rings by 0.2001 (14) and… (More)
