Abstract:
In the title compound, C9H13Cl2NO2, the piperidine ring shows a chair conformation and the O-C-C-O torsion angle between the carbonyl groups is 183.6 (4)°. In the crystal, mol-ecules are linked into an infinite layer along the ab plane by a bifurcated C-H⋯O hydrogen bond between the carbonyl O atom adjacent to the methyl group and one of the methyl-ene groups next to nitro-gen and an additional hydrogen bond of the C-H⋯Cl type. These layers are connected into a three-dimensional supra-molecular arrangement by O⋯Cl contacts [2.8979 (12) and 3.1300 (12) Å].

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...
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...
