1,4,5,8-Tetra-n-butyl-anthracene.
Summary
This study reveals the unique crystal structure of a C(30)H(42) molecule, featuring stair-like conformations and slipped-parallel arrangements without pi-pi stacking, offering insights into molecular packing.
Area of Science:
- Crystallography
- Organic Chemistry
- Materials Science
Background:
- Understanding molecular conformation and packing is crucial for designing novel organic materials.
- Anthracene derivatives are widely studied for their electronic and optical properties.
Purpose of the Study:
- To elucidate the crystal structure and molecular arrangement of the title compound, C(30)H(42).
- To investigate the influence of n-butyl side chains on the overall molecular shape and intermolecular interactions.
Main Methods:
- Single-crystal X-ray diffraction analysis was employed to determine the three-dimensional structure.
- Analysis of bond lengths, bond angles, and torsion angles provided insights into molecular geometry.
Main Results:
- The C(30)H(42) molecule possesses a unique stair-like shape due to the conformation of its four n-butyl side chains.
- The alkyl planes are nearly orthogonal to the central anthracene plane.
- Molecules arrange in a slipped-parallel fashion in the crystal lattice, notably lacking pi-pi stacking.
Conclusions:
- The specific arrangement of n-butyl chains dictates the molecule's overall conformation and crystal packing.
- The absence of pi-pi stacking in this slipped-parallel arrangement may influence the material's bulk properties.

01:13Five-Membered Heterocyclic Aromatic Compounds: Overview
Heterocyclic aromatic compounds are cyclic compounds that are aromatic and have one or more heteroatoms—atoms other than carbon, in the ring. Depending upon the number of atoms present in the ring, they can be either five or six-membered. Examples of five-membered heterocyclic aromatic compounds include pyrrole, furan, thiophene, and imidazole. Pyrrole consists of one nitrogen atom having one lone pair of electrons. Furan and thiophene have one oxygen and one sulfur heteroatom, respectively.
01:18Aromatic Hydrocarbon Anions: Structural Overview
Neutral hydrocarbons like cyclopentadiene with an odd number of carbon atoms and one intervening CH2 group in the ring are not aromatic. Cyclopentadiene with 4 π electrons does not satisfy the 4n + 2 π electron rule. Additionally, the intervening CH2 group is sp3 hybridized and lacks a vacant p orbital, thereby interrupting the overlap of p orbitals in a continuous manner and preventing the delocalization of π electrons throughout the ring.

01:18Aromatic Hydrocarbon Cations: Structural Overview
Cycloheptatriene is a neutral monocyclic unsaturated hydrocarbon that consists of an odd number of carbon atoms and an intervening sp3 carbon in the ring. The three double bonds in the ring correspond to 6 π electrons, which is a Huckel number, and therefore satisfies the criteria of 4n + 2 π electrons. However, the intervening sp3 carbon disrupts the continuous overlap of p orbitals. As a result, cycloheptatriene is not aromatic.

02:39Nomenclature of Alkynes
Alkynes are unsaturated hydrocarbons characterized by the presence of carbon-carbon triple bonds and have a general formula CnH2n-2. The nomenclature of alkynes follows a set of rules similar to alkanes and alkenes; however, alkynes bear the suffix "-yne" instead of "-ane" or "-ene." There are two approaches to naming alkynes:
01:29UV–Vis Spectroscopy: Woodward–Fieser Rules
UV–Visible absorption spectra of conjugated dienes arise from the lowest energy π → π* transitions. The light-absorbing part of the molecule is called the chromophore, and the substituents directly attached to the chromophore are called auxochromes. A strong correlation exists between the absorption maxima, λmax, and the structure of a conjugated π system. The Woodward–Fieser rules predict the value of λmax for a given structure by adding the contributions...
01:20Criteria for Aromaticity and the Hückel 4n + 2 Rule
Like benzene, cyclobutadiene and cyclooctatetraene are cyclic compounds with alternate single and double bonds. However, their chemical behavior differs from benzene, as they are unstable and not aromatic. So, what are the structural characteristics of unsaturated compounds categorized as aromatic?
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.
