Ammonia-triphenyl-borane

Area of Science:

• Crystal Chemistry
• Supramolecular Chemistry
• Materials Science

Background:

• Triphenylborane ammonia complex, (C(6)H(5))(3)B·NH(3), is a compound with potential applications in various chemical processes.
• Understanding the solid-state structure and intermolecular interactions is crucial for predicting and controlling material properties.

Purpose of the Study:

• To elucidate the crystal structure of the title compound, C(18)H(18)BN.
• To investigate the role of N-H⋯π and C-H⋯π interactions in the self-assembly of the molecular units.

Main Methods:

• Single-crystal X-ray diffraction analysis was employed to determine the molecular and crystal structure.
• Analysis of intermolecular contacts, including hydrogen bonding and π-π stacking, was performed.

Main Results:

• The asymmetric unit contains two independent, nearly identical molecules of triphenylborane ammonia complex.
• Molecules self-assemble into infinite columns along the b-axis via N-H⋯π interactions.
• These columns are further interconnected by C-H⋯π interactions, forming an extensive three-dimensional network.

Conclusions:

• The crystal structure is dictated by a combination of N-H⋯π and C-H⋯π supramolecular interactions.
• The observed 3D array highlights the importance of weak interactions in directing the assembly of organic-inorganic hybrid compounds.
