Abstract:
The mol-ecule of the title compound, C(18)H(18)Cl(2)N(2)O(2), lies across a crystallographic inversion centre and adopts an E configuration with respect to the azomethine C=N bond. The imino group is coplanar with the aromatic ring. Within the mol-ecule, the planar units are parallel, but extend in opposite directions from the dimethyl-ene bridge. In the crystal structure, the title compound exhibits a layer packing structure via weak π-π stacking inter-actions [inter-molecular plane-to-plane distances between adjacent aromatic rings are 3.461 (3) Å]. Mol-ecules in each layer are linked by inter-molecular C-H⋯O hydrogen-bonding inter-actions.

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
Stability of Conjugated Dienes
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.

π Molecular Orbitals of 1,3-Butadiene
The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the number...
