title: (E)-N'-(2,4,6-Trimethyl-benzyl-idene)isonicotinohydrazide.
abstract: The title isoniazid derivative, C(16)H(17)N(3)O, exists in an E configuration with respect to the Schiff base C=N bond. The pyridine ring is essentially planar [maximum deviation = 0.009 (3) Å]. The mean plane through the hydrazide unit forms dihedral angles of 38.38 (16) and 39.42 (16)°, respectively, with the pyridine and benzene rings. In the crystal structure, symmetry-related mol-ecules are linked via inter-molecular N-H⋯O hydrogen bonds into chains along [100]. The crystal structure is further stabilized by weak inter-molecular C-H⋯π inter-actions.
