The reaction of excess NaBH4 with N-(o-hydrazonylpyridine)ferrocenylimine (
L) in a THF/water mixture yields the borane adduct. LBH3, which has been ch
aracterised by IR and NMR spectroscopy. The single-crystal X-ray determinat
ion shows that the pyridine nitrogen of L is coordinated to the BH3 unit wi
th a B-N length of 1.596(3) Angstrom. (C) 2000 Elsevier Science S.A. All ri
