(1-Adamant-yl)diphenyl-methano-l

Area of Science:

• Organic Chemistry
• Crystallography
• Molecular Structure

Background:

• Adamantane derivatives are significant in materials science and medicinal chemistry.
• Understanding the precise three-dimensional structure of organic molecules is crucial for predicting their properties and reactivity.
• The presence of a hydroxyl group suggests potential for intermolecular interactions, such as hydrogen bonding.

Purpose of the Study:

• To elucidate the detailed crystal structure of the organic compound C(23)H(26)O.
• To analyze the geometric parameters of the adamantane cage and the orientation of its phenyl substituents.
• To investigate the presence or absence of hydrogen bonding in the solid state.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of bond lengths, bond angles, and dihedral angles was performed.
• Intermolecular interactions, specifically hydrogen bonding, were examined based on crystallographic data.

Main Results:

• The adamantane cage exhibits three fused cyclohexane rings in chair conformations.
• The C-C-C bond angles within the cage range from 106.57(11)° to 111.56(12)°.
• The dihedral angle between the two phenyl rings is 81.38(4)°, and no hydrogen bonds were observed despite the hydroxyl group.

Conclusions:

• The crystal structure of C(23)H(26)O has been successfully determined.
• The observed geometry provides insights into the conformational preferences of adamantane derivatives with phenyl substituents.
• The lack of hydrogen bonding in the crystal structure is an important finding for understanding intermolecular forces in this compound.
