5-(5-Bromo-2-methoxyphenyl)-2-fluoropyridine
In the title compound, C(12)H(9)BrFNO, the dihedral angle between the aromatic rings is 51.39 (5)°; the C atom of the meth-oxy group is close to being coplanar with its attached ring (r.m.s. deviation = 0.0172 Å] and is oriented away from the pyridine ring. In the crystal, mol-ecules inter-act by van der Waals forces.

The title compound, C(7)H(4)BrNO, crystallizes with two mol-ecules in the asymmetric unit. The two molecules exhibit nearly linear C-C N nitrile bond angles of 179.1 (4) and 177.1 (4)°. In the crystal, the mol-ecules are linked into a one-dimensional hydrogen-bonded chain by inter-actions between the phenol H atom and the nitrile N atom [N⋯O = 2.805 (4) and 2.810 (4) Å].

In the title compound, C7H4BrFO, the benzaldehyde O atom is found to be trans to the 2-bromo substituent. In the crystal, short Br⋯F inter-actions between the bromine and fluorine substituents are observed at distances of 3.1878 (14), 3.3641 (13) and 3.3675 (14) Å. Offset face-to-face π-stacking inter-actions are also observed for both of the independent mol-ecules in the asymmetric unit runnin...
متن کاملSecond derivative spectrophotometric method for simultaneous determination of cobalt, nickel and iron using 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol.
A simple, sensitive and rapid derivative spectrophotometric method using 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP) has been developed for simultaneous determination of Co(II), Ni(II) and Fe(II) which have very similar chemical behavior and appear together in many real samples. The complexes of all these metal ions with 5-Br-PADAP were formed immediately at pH 7.0 ammonium aceta...
متن کاملCrystal 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...
