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 کاملThree-dimensional quantitative structure activity relationship approach series of 3-Bromo-4-(1-H-3-Indolyl)-2, 5-Dihydro-1H-2, 5- Pyrroledione as antibacterial agents
The use of quantitative structure–activity relationships, since its advent, has becomeincreasingly helpful in understanding many aspects of biochemical interactions in drug research.This approach was utilized to explain the relationship of structure with biological activity ofantibacterial. For the development of new fungicides against, the quantitative structural–activityrelationship (QSAR) an...
متن کامل5-Amino-4-bromo-2,3-dihydro-1H-inden-1-one
In the title compound, C(9)H(8)BrNO, the non-H-atom framework is essentially planar, with a maximum deviation of 0.087 (3) Å. In the crystal, mol-ecules are inter-connected into a three-dimensional network by C-H⋯O and N-H⋯O hydrogen bonds. In addition, C-H⋯π inter-actions and a π-π stacking inter-action, with a centroid-centroid distance of 3.5535 (19) Å, are also observed.
متن کامل5-Bromo-2,3-dihydro-1H-cyclopenta[a]naphthalen-1-one
The title compound, C(13)H(9)BrO, has been synthesized by the intra-molecular Friedel-Crafts reaction of 1-(1-bromo-4-naphth-yl)-3-chloro-propan-1-one. There are two approximately planar [maximum deviations of 0.8 (2) and 0.4 (2) Å in the two mol-ecules] molecules in the asymmetric unit. The dihedral angle between their mean planes is 19.72 (8)°. Weak inter-molecular C-H⋯O hydrogen bonding is p...
