Summary
This study details the crystal structure of a carbazole derivative, revealing a near-planar carbazole core with a twisted methoxy-substituted phenyl ring. Molecular packing is dominated by hydrogen-hydrogen and carbon-hydrogen interactions.
Area of Science:
- Crystallography
- Organic Chemistry
- Materials Science
Background:
- Carbazole derivatives are important in organic electronics and medicinal chemistry.
- Understanding the solid-state structure is crucial for predicting material properties.
Purpose of the Study:
- To elucidate the crystal structure of a novel carbazole derivative (C19H15NO).
- To analyze the molecular conformation and intermolecular interactions within the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Hirshfeld surface analysis was used to quantify intermolecular interactions.
Main Results:
- The carbazole moiety exhibits a dihedral angle of 1.73(12)° between its benzene rings.
- The methoxy-substituted phenyl ring deviates significantly from the carbazole mean plane (56.78(8)°).
- Hirshfeld surface analysis revealed that H⋯H (51.2%) and C⋯H/H⋯C (39.9%) contacts are the primary contributors to crystal packing.
Conclusions:
- The study provides detailed structural insights into a specific carbazole derivative.
- The observed molecular conformation and packing interactions offer a basis for designing related materials with tailored properties.

Aromatic Hydrocarbon Cations: Structural Overview
2.8K
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.

Carbocations
11.3K
Carbocations are one of the reaction intermediates formed during several nucleophilic substitutions or elimination reactions. A carbocation is an electron-deficient species with the central carbon atom having six electrons and three bonded atoms. The central carbon in a carbocation is sp2 hybridized with trigonal planar geometry. It has an empty p orbital perpendicular to the plane of the structure that can accept electrons. Thus, carbocations act as strong electrophiles and may react with any...

Five-Membered Heterocyclic Aromatic Compounds: Overview
4.0K
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,...

NMR Spectroscopy of Benzene Derivatives
8.4K
Simple unsubstituted benzene has six aromatic protons, all chemically equivalent. Therefore, benzene exhibits only a singlet peak at δ 7.3 ppm in the 1H NMR spectrum. The observed shift is far downfield because the aromatic ring current strongly deshields the protons. Any substitution on the benzene ring makes the aromatic protons nonequivalent, and the protons split each other. The peak is, therefore, no longer a singlet and the splitting pattern and their associated coupling...

IUPAC Nomenclature of Carboxylic Acids
9.6K
IUPAC names of carboxylic acids are systematically derived following a few rules discussed below.
For acyclic saturated monocarboxylic acids, the longest hydrocarbon chain containing the –COOH carbon is identified as the parent chain. Then, the last -e of the parent hydrocarbon name is replaced with a suffix -oic acid.
