2-Bromo-3-nitrobenzaldehyde
The title compound, C(7)H(4)BrNO(3), was isolated as a by-product while attempting to prepare a diselenide. There is a close intra-molecular Br⋯O contact [2.984 (2) Å]. The mol-ecules form loosely associated dimers held together by weak inter-molecular Br⋯O inter-actions with the nitro O atoms [Br⋯O = 3.179 (3) Å]. As a result of these inter-actions, there is also a close Br⋯Br inter-molecular ...
متن کامل3-Bromo-2-hydroxybenzaldehyde
The mol-ecule of the title compound, C(7)H(5)BrO(2), is almost planar (r.m.s. deviation from the plane of all the non-H atoms = 0.0271 Å) and displays intra-molecular O-H⋯O hydrogen bonding between the phenol group and the aldehyde O atom. Packing is directed by weak inter-molecular C-H⋯Br inter-actions and π-stacking between nearly parallel mol-ecules [dihedral angle = 5.30 (6)° and centroid-c...

The title compound, C(14)H(10)Br(2)N(2)O(2), was synthesized by the reaction of 5-bromo-salicylaldehyde with an equimolar quantity of 3-bromo-benzohydrazide in methanol. The dihedral angle between the two benzene rings is 10.5 (4)°. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds to form chains parallel to the c axis, and an intra-molecular O-H⋯N int...
متن کاملMethyl 5-bromo-2-chloropyridine-3-carboxylate
The title compound, C(7)H(5)BrClNO(2), crystallizes with two independent molecules in the asymmetric unit. In the absence of classical inter-molecular inter-actions, the crystal structure exhibits relatively short inter-molecular Br⋯O distances [3.143 (9) and 3.162 (9)Å].
متن کامل(E)-4-Bromo-N-{(E)-3-[(4-bromo-2-methylphenyl)imino]butan-2-ylidene}-2-methylaniline
The title compound, C(18)H(18)Br(2)N(2), is centrosymmetric with the mid-point of the central C-C bond of the butyl group located on an inversion center. The terminal benzene ring is approximately perpendicular to the central butyl plane [dihedral angle = 71.9 (8)°]. No hydrogen bonding or aromatic stacking is observed in the crystal.
