چکیده
The title Schiff base compound, C(15)H(14)BrNO(2), adopts an E configuration with respect to the C=N bond. The C and O atoms of the two meth-oxy substituents lie very close to the dimethoxy-phenyl ring plane [maximum deviation = 0.17 (1) Å]. The dihedral angle between the two aromatic rings is 43.69 (16)°, while the plane through the central C-C=N-C system is inclined at 10.6 (6)° to the dimethoxy-phenyl ring and 34.6 (3)° to the bromo-phenyl ring. In the crystal structure, each mol-ecule is involved in the formation of two inversion-related dimers through weak C-H⋯N and C-H⋯O inter-actions, respectively. These contacts link the mol-ecules into independent rows parallel to the b axis.
