The asymmetric unit of the title compound, C(18)H(18)BN or (C(6)H(5))(3)B·NH(3), comprises two crystallographically independent but virtually identical mol-ecules. Mol-ecules of one type are linked with each other by N-H⋯π inter-actions, generating an infinite column aligned along the b-axis direction.

Electrochemical Ammonia Synthesis and Ammonia Fuel Cells
AbstractAmmonia is a promising platform molecule for the future renewable energy infrastructure owing to its high energy density (when liquefied) and carbon‐free nature. In particular, the interconversion between the chemical and electrical energies leveraging the nitrogen cycle could be an effective approach in mitigating the intermittency of ...
