N'-[(1E,2E)-3,7-Dimethyl-octa-2,6-dien-1-yl-idene]pyridine-4-carbohydrazide.

ABSTRACT: In the title compound, C(16)H(21)N(3)O, the mol-ecule adopts an E conformation about the central C=N double bond. The 2-methyl-pent-2-ene group is disordered over two sets of sites, with a refined occupancy ratio of 0.785?(8):0.215?(8). The dihedral angle between the essentially planar [the r.m.s. value for the major component is 0.021?(7) and its maximum deviation is 0.025?(4)?Å; the r.m.s. value for the minor component is 0.03?(4) and its maximum deviation is 0.05?(3)?Å] major and minor components of the 2-methyl-but-2-ene group is 35.9?(13)°. In the crystal, C-H?O and N-H?O hydrogen bonds link the molecules, with the same O atom acting as the acceptor. This results in C(1) (1)(4) and C(1) (1)(5) [001] chains.
