N'-(2,4-Dichloro-benzyl-idene)-3-methoxy-benzohydrazide

Area of Science:

• Crystallography
• Organic Chemistry
• Solid-State Chemistry

Background:

• Understanding the three-dimensional structure of organic molecules is crucial for predicting their properties and reactivity.
• Crystal structure analysis provides detailed insights into molecular conformation and intermolecular interactions.
• The specific compound C(15)H(12)Cl(2)N(2)O(2) has not been extensively studied in terms of its solid-state behavior.

Purpose of the Study:

• To determine and characterize the crystal structure of the title compound, C(15)H(12)Cl(2)N(2)O(2).
• To analyze the conformational differences between the two independent molecules in the asymmetric unit.
• To investigate the intermolecular interactions governing the crystal packing.

Main Methods:

• Single-crystal X-ray diffraction was employed to collect diffraction data.
• The crystal structure was solved and refined using standard crystallographic software.
• Analysis of bond lengths, bond angles, dihedral angles, and intermolecular interactions was performed.

Main Results:

• The asymmetric unit contains two independent molecules of C(15)H(12)Cl(2)N(2)O(2).
• Significant differences in the dihedral angles between the two benzene rings were observed (27.6° vs 16.4°).
• Both molecules exhibit an E configuration around the C=N bonds, and intermolecular N-H⋯O hydrogen bonds form chains along the a-axis.

Conclusions:

• The crystal structure of C(15)H(12)Cl(2)N(2)O(2) reveals conformational diversity within the asymmetric unit.
• Intermolecular hydrogen bonding plays a key role in organizing the molecules into one-dimensional chains.
• These findings contribute to the understanding of structure-property relationships in related organic compounds.
