1,2-Di-hydro-spiro-[carbazole-3(4H),2'-[1,3]dioxolane]

Area of Science:

• Organic Chemistry
• Crystallography
• Supramolecular Chemistry

Background:

• Carbazole derivatives are important scaffolds in materials science and medicinal chemistry.
• Understanding the solid-state structure is crucial for predicting and tuning material properties.

Purpose of the Study:

• To elucidate the crystal structure and intermolecular interactions of a novel carbazole derivative (C14H15NO2).
• To analyze the conformational preferences of the carbazole and dioxolane rings.
• To investigate the packing motifs and hydrogen bonding in the solid state.

Main Methods:

• Single-crystal X-ray diffraction analysis was performed.
• Conformational analysis of the molecular structure was conducted.
• Intermolecular interactions, including hydrogen bonding and pi-pi stacking, were examined.

Main Results:

• The hydrogenated carbazole ring adopts a half-chair conformation.
• The dioxolane ring is oriented unilaterally relative to the carbazole plane.
• Edge-to-face interactions between neighboring molecules form 1D herringbone motifs.
• Shortest H⋯C contacts of 2.72 Å (NH⋯carbazole) and 2.85 Å (CH2⋯carbazole) were observed.

Conclusions:

• The study provides a detailed structural characterization of the carbazole derivative.
• The observed intermolecular interactions dictate the crystal packing and supramolecular assembly.
• These findings contribute to the understanding of structure-property relationships in carbazole-based compounds.
