(E)-2,4-Dimethyl-N'-(2-methyl-benzyl-idene)benzohydrazide

Area of Science:

• Organic Chemistry
• Crystallography

Background:

• Benzoyl-hydrazide derivatives are important organic compounds with diverse applications.
• Understanding their solid-state structure is crucial for predicting their chemical behavior and properties.

Purpose of the Study:

• To elucidate the crystal structure of the title benzoyl-hydrazide derivative (C17H18N2O).
• To analyze the molecular conformation and intermolecular interactions within the crystal lattice.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of bond lengths, bond angles, and intermolecular interactions (hydrogen bonds) was performed.

Main Results:

• The crystal structure revealed a dihedral angle of 88.45(8)° between the two benzene rings.
• The azomethine double bond was confirmed to adopt an E conformation.
• N-H⋯O and C-H⋯O hydrogen bonds were identified, linking molecules into chains along the b axis.

Conclusions:

• The determined crystal structure provides detailed insights into the solid-state arrangement of this benzoyl-hydrazide derivative.
• The observed hydrogen bonding network is key to the formation of extended molecular chains in the crystal structure.
