4-(1H-2,3-Dihydronaphtho­[1,8-de][1,3,2]di­aza­borinin-2-yl)-1-ethylpyridin-1-ium iodide monohydrate

Abstract

The cation of the title hydrated salt is a di­aza­borinane featuring substitution at 1, 2, and 3 positions in the nitro­gen–boron six-membered heterocycle. In the crystal, the cations stack along [100] in an alternating head-to-tail manner, while the iodide ion and water mol­ecule form one-dimensional hydrogen-bonded chains beside the cation stack. The cation stacks and I⁻–water chains are crosslinked by N—H⋯I and N—H⋯O hydrogen bonds.

The cation of the title hydrated salt, C₁₇H₁₇BN₃ ⁺·I⁻·H₂O, is a di­aza­borinane featuring substitution at the 1, 2, and 3 positions in the nitro­gen–boron six-membered heterocycle. The cation is approximately planar with a dihedral angle between the pyridyl ring and the di­aza­borinane ring system of 5.40 (5)°. In the crystal, the cations stack along [100] in an alternating head-to-tail manner, while the iodide ion and water mol­ecule form one-dimensional hydrogen-bonded chains beside the cation stack. The cation stacks and I⁻–water chains are crosslinked by N—H⋯I and N—H⋯O hydrogen bonds.
