N′-[4-(Dimethylamino)benzylidene]benzohydrazide

Abstract

In the title mol­ecule, C16H17N3O, the two aromatic rings form a dihedral angle of 4.51 (18)°. In the crystal structure, inter­molecular N—H⋯O hydrogen bonds link mol­ecules related by translation along the a axis into ribbons.

(E)-4-[(4-Bromobenzylidene)amino]phenol

“…The geometric parameters of the title compound ( Fig. 1) agree well with reported similar structures (Cui et al, 2009;Sun et al, 2009). The dihedral angle between the benzene rings is 35.20 (8)°.…”
