Diethyl [hydr-oxy(phen-yl)meth-yl]phospho-nate

Area of Science:

• Crystal Chemistry
• Supramolecular Chemistry
• Organic Phosphorus Chemistry

Background:

• Understanding the self-assembly of organic molecules is crucial for designing novel materials.
• Hydrogen bonding plays a significant role in dictating crystal packing and molecular architecture.

Purpose of the Study:

• To elucidate the crystal structure and intermolecular interactions of the title compound, C(11)H(17)O(4)P.
• To investigate the role of hydrogen bonding in the formation of supramolecular architectures.

Main Methods:

• Single-crystal X-ray diffraction analysis was employed to determine the molecular and crystal structure.
• Analysis of hydrogen bonding networks and identification of disordered moieties.

Main Results:

• Molecules of C(11)H(17)O(4)P self-assemble into chiral helical chains along the crystallographic b axis.
• O-H⋯O hydrogen bonds between hydroxyl and phosphonate groups facilitate the formation of these helical chains.
• One ethyl group displays positional disorder with site occupancy factors of approximately 0.7 and 0.3.

Conclusions:

• The study demonstrates the formation of one-dimensional chiral supramolecular chains driven by hydrogen bonding.
• The observed disorder in the ethyl group provides insights into conformational flexibility within the crystal lattice.
