The title compound, C15H12BN3, is a type of di-aza-borinane featuring substitution at 1, 2, and 3 positions in the nitro-gen-boron six-membered heterocycle. It is comprised of two almost planar units, the pyridyl ring and the Bdan (dan = 1,8-di-aminona-phtho) group, which subtend a dihedral angle of 24.57 (5)°. In the crystal, the mol-ecules are linked into R 4 4(28) hydrogen-bonding networks around the fourfold inversion axis, giving cyclic tetra-mers. The mol-ecules form columnar stacks along the c axis.
Keywords: crystal structure; dan; pyridine derivative; tetrameric structure.
