The synthesis of a ferrocenyl Schiff base pyridine borane complex using NaBH4

The reaction of excess NaBH4 with N-(o-hydrazonylpyridine)ferrocenylimine (L) in a THF/water mixture yields the borane adduct, LBH3, which has been characterised by IR and NMR spectroscopy. The single-crystal X-ray determination shows that the pyridine nitrogen of L is coordinated to the BH3 unit with a B–N length of 1.596(3) Å.
