2-[(E)-(2,4-Dimethyl-phen-yl)imino-meth-yl]phenol.

Area of Science:

• Crystallography
• Organic Chemistry
• Molecular Structure

Background:

• Understanding the three-dimensional arrangement of atoms in organic molecules is crucial for predicting their properties and reactivity.
• The study of intermolecular forces, such as hydrogen bonding, provides insights into crystal packing and solid-state behavior.

Purpose of the Study:

• To elucidate the crystal structure of the title compound, C15H15NO.
• To characterize the molecular geometry, including bond configurations and dihedral angles.
• To identify and describe intra- and intermolecular interactions within the crystal.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the crystal structure.
• Analysis of bond lengths, bond angles, and dihedral angles provided detailed molecular geometry.
• Identification of hydrogen bonding networks (intra- and intermolecular) was performed.

Main Results:

• The asymmetric unit contains two independent molecules of C15H15NO.
• Both molecules exhibit trans configurations around the C=N bonds, with specific bond lengths reported.
• Intramolecular O-H⋯N hydrogen bonds form S(6) ring motifs in each molecule.
• Dihedral angles between benzene rings differ between the two independent molecules (13.38(9)° and 30.60(10)°).
• Weak intermolecular C-H⋯O hydrogen bonds link the independent molecules in the crystal.

Conclusions:

• The crystal structure of C15H15NO reveals the presence of two distinct molecular conformations in the solid state.
• Intramolecular hydrogen bonding plays a significant role in stabilizing the individual molecular structures.
• Intermolecular interactions contribute to the overall crystal packing arrangement.
