Area of Science:

• Organic Chemistry
• Crystallography
• Molecular Structure

Background:

• Vanillin derivatives are important in medicinal chemistry and materials science.
• Schiff bases, formed from aldehydes and amines, are versatile chemical intermediates.
• Understanding molecular conformation and crystal packing is crucial for predicting material properties.

Purpose of the Study:

• To synthesize and characterize a novel compound derived from o-vanillin and aniline.
• To elucidate the tautomeric form and conformational properties of the synthesized molecule.
• To investigate the intermolecular interactions and crystal packing of the title compound.

Main Methods:

• Condensation reaction between o-vanillin and aniline in ethanol.
• Spectroscopic analysis (implied, not explicitly stated).
• Single-crystal X-ray diffraction to determine molecular and crystal structure.

Main Results:

• The title compound, C(14)H(13)NO(2), was successfully synthesized.
• The molecule exists in the phenol-imine tautomeric form with an E conformation around the C=N bond.
• A dihedral angle of 30.57° between aromatic rings was observed.
• Intermolecular C-H⋯O hydrogen bonds link molecules into zigzag chains along the b axis.

Conclusions:

• The synthesis yielded the target Schiff base compound.
• The structural analysis reveals specific tautomeric and conformational preferences.
• The observed crystal packing highlights the role of hydrogen bonding in directing self-assembly.
