Area of Science:

• Crystallography
• Organic Chemistry
• Materials Science

Background:

• Understanding molecular structure and intermolecular interactions is crucial for predicting material properties.
• The specific molecule C(19)H(31)N(2)O(2)P has not been previously characterized in detail.
• Phosphorus-containing organic molecules can exhibit unique chemical and physical properties.

Purpose of the Study:

• To elucidate the crystal structure of the molecule C(19)H(31)N(2)O(2)P.
• To analyze the coordination geometry around the phosphorus atom.
• To investigate the intermolecular interactions, specifically hydrogen bonding, 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 torsion angles provided insights into the molecular geometry.
• Identification and analysis of intermolecular hydrogen bonds were performed.

Main Results:

• The phosphorus (P) atom in C(19)H(31)N(2)O(2)P adopts a distorted tetrahedral configuration.
• Observed P-X bond angles range from 101.48(10)° to 118.58(9)°.
• Molecules self-assemble into chains along the a-axis via two distinct intermolecular N-H⋯O(P) hydrogen bonds, with the P=O oxygen acting as a double acceptor.

Conclusions:

• The crystal structure reveals a unique distorted tetrahedral geometry around the phosphorus atom.
• Intermolecular hydrogen bonding plays a significant role in the self-assembly of these molecules into one-dimensional chains.
• The findings provide fundamental structural data for C(19)H(31)N(2)O(2)P, relevant for further studies in organic chemistry and materials science.
