%X In the title compound, C20H14BNO2, the B atom has a tetrahedral geometry with two short B¡ªO and two long B¡ªC and B¡ªN bonds, revealing a significant difference between Car¡ªO¡ªB and Calkyl¡ªO¡ªB bond distances. Intermolecular Ar¡ªH...O hydrogen bonds and strong ¦Ð¨C¦Ð interactions (3.368  ) between aromatic cores of neighbouring molecules result in hexagonal channels along the crystallographic c axis, which are potentially accessible for small molecules.
