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.1917–1920enopenAccessCrystal structureB-phenyl-­dioxaza-­borocineN—B dative bondZwitterionic heterocycleC—H⋯O inter­actionsarticuloLedesma, Gabriela N.Signorella, Sandra R.Back, DaviSchulz Lang, ErnestoUniversidad Nacional de Rosario.
