2-(6-Bromo­pyridin-2-yl)-6-methyl-[1,3,6,2]­diox­aza­borocane, a new stable (pyridin-2-yl)­boronic acid derivative

The crystal structure of the first reported non-substituted N-methyl­diox­aza­borocane confirms that the presence of a methyl group attached to the N atom introduces an NB bond length that is longer than that in a simple diox­aza­borocane ring. The presence of more N atoms in the vicinity of the B atom in the title compound [systematic name: 6a-(6-bromo­pyridin-2-yl)-3a-methyl-2,3,4,5-tetra­hydro-1,6-dioxa-3a-aza-6a-borapentalene], C₁₀H₁₄BBrN₂O₂, does not modify significantly any structural parameter in the diox­aza­borocane ring. On the other hand, a small asymmetry appears in the bond angles of the pyridine C atom next to the B atom.
