Abstract:
The cation of the title hydrated salt, C17H17BN3 +·I-·H2O, is a di-aza-borinane featuring substitution at the 1, 2, and 3 positions in the nitro-gen-boron six-membered heterocycle. The cation is approximately planar with a dihedral angle between the pyridyl ring and the di-aza-borinane 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 mol-ecule 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.
