The title compound, C(11)H(8)Br(2)N(4), is a Schiff base obtained from 6-bromo-picolinaldehyde and 5-bromo-pyridine-3,4-diamine. The mol-ecule has an E configuration about the C=N bond and the dihedral angle between the two pyridine rings is 14.02 (1)°. The observed conformation is stabilised by an intramolecular N-H⋯N hydrogen bond. In the crystal, mol-ecules are stacked along the b axis and a...
متن کاملN,N′-Bis(5-bromo-2-hydroxybenzylidene)-2,2-dimethylpropane-1,3-diamine
The crystal structure of the title Schiff base compound, C(19)H(20)Br(2)N(2)O(2), contains two crystallographically independent mol-ecules (A and B) in the asymmetric unit, with similar conformations. Intra-molecular O-H⋯N (× 4) and C-H⋯N (× 5) hydrogen bonds form six- and five-membered rings, producing S(6) and S(5) ring motifs, respectively. One of the N atoms in mol-ecule A acts as a trifurc...
متن کاملN,N′-Bis(4-bromo-2-fluorobenzylidene)ethane-1,2-diamine
The mol-ecule of the title Schiff base compound, C(16)H(12)Br(2)F(2)N(2), lies across a crystallographic inversion centre and adopts an E configuration with respect to the azomethine C=N bonds. The imino groups are coplanar with the aromatic rings. Within the mol-ecule, the planar units are parallel, but extend in opposite directions from the dimethyl-ene bridge. An inter-esting feature of the ...
متن کامل5-Bromo-2-hydroxybenzonitrile
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].
