(2E,6E)-2,6-Bis(2,4,5-trimethoxy-benzyl-idene)cyclo-hexa-none
Abstract:
In the title compound, C(26)H(30)O(7), one atom in the cyclo-hexa-none ring is disordered over two positions with a site-occupancy ratio of 0.871 (6):0.129 (6). The dihedral angles formed between the mean plane through the six C atoms of the major component of the cyclo-hexa-none ring and two benzene rings are 35.09 (10) and 34.21 (10)°; the corresponding angles for the minor component are 20.1 (2) and 19.5 (2)°. Both the major and minor disordered components of the cyclo-hexa-none ring adopt half-boat conformations. In the crystal packing, inter-molecular C-H⋯O hydrogen bonds connect the mol-ecules into a three-dimensional network.

Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.

Criteria for Aromaticity and the Hückel 4n + 2 Rule
For the first time, Eric Hückel, a German chemical physicist, derived a set of structural features for a compound to be classified as aromatic. This is now known as Hückel’s rule or the 4n + 2 rule.
