{2-Hydroxy-6-[(2-oxidophenyl)iminomethyl-κ²N,O]phenolato-κO¹}phenylboron

Abstract

The [4.3.0]heterobicyclic title structure, C19H14BNO3, is composed of a five-membered OBNC2 ring and a six-membered OBNC3 ring, each of which has an approximate envelope conformation. The coordination geometry of the B atom is distorted tetra­hedral. In the crystal structure, centrosymmetrically related mol­ecules are associated through pairs of O—H⋯O hydrogen bonds.
