One boron—chlorine bond perpendicular to the plane of the ring is significantly longer than the in‐plane BCl bond—this is the surprising result of the X‐ray structure analysis of the BNP heterocycle 1 . The zwitterion 1 reacts with GaCl 3 under halide abstraction to give 2 , which possesses the first authentic hybrid borazine—phosphazene ring [Eq. (a)].
