Abstract
Reactions of niobium tetraiodide with sterically hindered beta-diketones in the presence of diethylamine gave eight-coordinate Nb(IV) complexes Nb(bet a-diket)(4). The thermal stability of the complexes at atmospheric pressure and in a vacuum and the nature of the hydrolysis and oxidation products we re studied. The possibility of using the complexes as precursors for prepar ing Nb(IV) oxide layers was examined.
