1,4,5,8-Tetra-isopropyl-anthracene.
Summary
This study reveals the crystal structure of a C(26)H(34) compound, showing molecules with inversion symmetry and a planar anthracene core. The arrangement avoids typical pi-pi stacking in its solid state.
Area of Science:
- Crystal engineering and solid-state chemistry.
- Organic molecular structure determination.
Background:
- Understanding molecular packing in crystals is crucial for predicting material properties.
- Anthracene derivatives are widely studied for their electronic and optical applications.
Purpose of the Study:
- To elucidate the crystal structure and molecular arrangement of the title compound C(26)H(34).
- To investigate the influence of isopropyl substituents on the packing of anthracene derivatives.
Main Methods:
- Single-crystal X-ray diffraction analysis was employed to determine the molecular and crystal structure.
- Analysis of bond lengths, bond angles, and intermolecular interactions.
Main Results:
- The C(26)H(34) molecules exhibit crystallographically imposed inversion symmetry.
- The anthracene core is planar, with isopropyl groups positioned on opposite sides of the plane.
- A herringbone-like packing arrangement was observed, notably lacking pi-pi stacking interactions.
Conclusions:
- The specific orientation of isopropyl groups dictates a non-stacking herringbone arrangement in the crystal lattice.
- This structural insight contributes to the understanding of structure-property relationships in substituted anthracenes.

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.
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:
01:18Aromatic 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.

01:29UV–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...
01:23Nomenclature of Aromatic Compounds with a Single Substituent
Benzene is the simplest aromatic hydrocarbon or arene. The IUPAC names for simple monosubstituted benzene derivatives are derived by adding the substituent's name as a prefix to the parent benzene. For example, halobenzene, where the halogen could be fluoro (F), chloro (Cl), bromo (Br), and iodo (I).
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.
