(4,9-Dimethyl-9H-carbazol-3-yl)meth-anol

Area of Science:

• Crystallography
• Organic Chemistry
• Materials Science

Background:

• Carbazole derivatives are important scaffolds in medicinal chemistry and materials science.
• Understanding the solid-state structure of organic molecules is crucial for predicting their properties and designing new materials.

Purpose of the Study:

• To elucidate the crystal structure of a novel carbazole derivative, C15H15NO.
• To investigate the intermolecular interactions governing the crystal packing.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of hydrogen bonding and other non-covalent interactions was performed.

Main Results:

• The carbazole skeleton with a 3-position methanol group was confirmed.
• The indole ring system exhibited near planarity (maximum deviation = 0.045(2) Å).
• O-H⋯O hydrogen bonds formed zigzag chains along the b-axis, complemented by weak C-H⋯π interactions creating sheets parallel to (001).

Conclusions:

• The crystal structure of C15H15NO reveals specific hydrogen bonding and C-H⋯π interactions.
• These interactions dictate the formation of 1D chains and 2D sheets, influencing the overall crystal packing.
• The findings contribute to the understanding of structure-property relationships in carbazole-based compounds.
