(E)-N′-(5-Bromo-2-methoxy­benzyl­idene)-3-methoxy­benzohydrazide

In the title compound, C(16)H(15)BrN(2)O(3), there are two independent mol­ecules (A and B) in the asymmetric unit. The major difference between the two mol­ecules is the dihedral angle formed by the aromatic rings [72.6 (2) and 18.8 (2)° for A and B, respectively]. The benzohydrazide groups are not...

description In the title compound, C(16)H(15)BrN(2)O(3), there are two independent mol­ecules (A and B) in the asymmetric unit. The major difference between the two mol­ecules is the dihedral angle formed by the aromatic rings [72.6 (2) and 18.8 (2)° for A and B, respectively]. The benzohydrazide groups are not planar and the mol­ecules exist in trans configurations with respect to the methyl­idene units. The mol­ecular packing is stabilized by two inter­molecular N—H⋯O hydrogen bonds, forming chains parallel to the c axis. Only the A mol­ecules of the asymmetric unit are held together by π–π inter­actions [centroid–centroid distance = 3.714 (3) Å].
