(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?? inter-actions.
