Crystal structure of (E)-3-(5-bromo-2-hydroxyphenyl)acrylaldehyde
The title compound, C9H7BrO2, displays a trans configuration with respect to the C=C double bond and is essentially planar [maximum deviation from the least-squares plane through all non-H atoms = 0.056 (4) Å]. The vinyl-aldehyde group adopts an extended conformation wih a C-C-C-C torsion angle of 179.7 (4)°. In the crystal, mol-ecules are linked by classical O-H⋯O and weak C-H⋯O hydrogen bonds...
متن کاملCrystal structure of (E)-1-(3-chlorophenyl)-3-(furan-2-yl)prop-2-en-1-one
The title compound, C13H9ClO2, exhibits a non-planar geometry; the furan ring being inclined to the benzene ring by 50.52 (16)°. In the crystal, mol-ecules stack along the a axis; however, there are no significant inter-molecular inter-actions present.
متن کاملCrystal structure of 3-[(E)-(2-hydroxy-3-methoxybenzylidene)amino]-1-methyl-1-phenylthiourea
In the asymmetric unit of the title compound, C16H17N3O2S, there are two independent mol-ecules (A and B), which show an E conformation with respect to the C=N bond. An intra-molecular O-H⋯N hydrogen bond with an S(6) motif stabilizes the mol-ecular structure. The terminal phenyl and benzene rings are almost orthogonal to each other, the dihedral angle being 87.47 (13)° for mol-ecule A and 89.8...

In the title compound, C9H9ClN2O, the ethynyl-pyrimidine moiety displays an almost planar geometry. In the crystal, mol-ecules are linked by O-H⋯N and C-Hpyrimidine⋯O hydrogen bonds, forming a three-dimensional supra-molecular architecture.
متن کاملCrystal structure of 3-(4-methylphenyl)-1-phenyl-5-[(E)-2-phenylethenyl]-1H-pyrazole
In the title compound, C24H20N2, the dihedral angles between the pyrazole ring and the pendant phenyl, toluoyl and phenyl-ethenyl rings are 41.50 (8), 4.41 (8) and 31.07 (8)°, respectively. In the crystal, inversion dimers linked by a π-π stacking inter-actions between the phenyl-ethenyl rings are observed [centroid-centroid separation = 3.5857 (9) Å].
