Area of Science:

• Crystallography
• Organic Chemistry
• Molecular Structure Analysis

Background:

• The study focuses on the molecular structure and bonding characteristics of a specific organic compound.
• Understanding the spatial arrangement and interactions within molecules is crucial for predicting chemical behavior.

Purpose of the Study:

• To elucidate the crystal structure of the title compound, C(16)H(16)N(2)O(3).
• To investigate the dihedral angles between aromatic rings and identify intramolecular hydrogen bonding patterns.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular structure.
• Analysis of crystallographic data to measure bond lengths, angles, and intermolecular interactions.

Main Results:

• The asymmetric unit contains two independent molecules of C(16)H(16)N(2)O(3).
• Dihedral angles between the aromatic rings were measured as 13.0(3)° and 6.4(3)° for the two molecules.
• Intramolecular hydrogen bonds (O-H⋯N and N-H⋯O) were observed in both molecules, forming S(6) rings.

Conclusions:

• The crystal structure reveals specific conformational preferences and hydrogen bonding networks in C(16)H(16)N(2)O(3).
• The identified hydrogen bonds contribute to the stability of the molecular conformation.
