Abstract

In the title compound, C20H14BNO2, the B atom has a tetra­hedral geometry with two short B—O and two long B—C and B—N bonds, revealing a significant difference between Car—O—B and Calk­yl—O—B bond distances. Inter­molecular Ar—H⋯O hydrogen bonds and strong π–π inter­actions (3.368 Å) between aromatic cores of neighbouring mol­ecules result in hexa­gonal channels along the crystallographic c axis, which are potentially accessible for small mol­ecules.
