2-(Pyridin-4-yl)-2,3-dihydro-1H-naphtho[1,8-de][1,3,2]diazaborinine

Abstract

The title compound, C15H12BN3, is a type of diazaborinane featuring substitution at 1, 2, and 3 positions in the nitrogen–boron six-membered heterocycle. It is comprised of two almost planar units, the pyridyl ring and the Bdan (dan = 1,8-diaminonaphtho) group, which subtend a dihedral angle of 24.57 (5)°. In the crystal, the molecules are linked into R44(28) hydrogen-bonding networks around the fourfold inversion axis, giving cyclic tetramers. The molecules form columnar stacks along the c axis.
