Diethyl 4,4'-{[1,2-phenyl-enebis(methyl-ene)]bis-(-oxy)}dibenzoate

Area of Science:

• Organic Chemistry
• Crystallography
• Molecular Structure

Background:

• Understanding the relationship between molecular structure and physical properties is crucial in chemistry.
• Organic compounds with benzoate moieties are widely studied for their diverse applications.

Purpose of the Study:

• To elucidate the three-dimensional structure of the title compound (C26H26O6).
• To investigate the conformational preferences and electronic properties influenced by molecular geometry.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular structure.
• Analysis of bond lengths, angles, and dihedral angles provided conformational insights.

Main Results:

• The title compound features two methyl-ene(-oxy)ethyl-benzoate groups attached to a central phenyl ring.
• One benzoate fragment is nearly coplanar with the phenyl ring, facilitating electron delocalization.
• A significant dihedral angle of 57.4(2)° exists between the phenyl ring and the second benzoate fragment.

Conclusions:

• The observed molecular conformation is influenced by intermolecular packing forces within the crystal lattice.
• The compound's structure suggests potential for interesting electronic properties due to partial coplanarity and electron delocalization.
