The title compound, C26H23BN2O2, was obtained as by product during synthetic attempts of a complexation reaction between the tripodal ligand H2L [N,N-bis(2-hydroxybenzyl)(pyridin-2-yl)methylamine] and manganese(III) acetate in the presence of NaBPh4. The isolated B-phenyl dioxazaborocine contains an N→B dative bond with a cis conformation. In the crystal, C—H⋯O hydrogen bonds define chains parallel to the b-axis direction. A comparative analysis with other structurally related derivatives is also included, together with a rationalization of the unexpected production of this zwitterionic heterocycle.
