“…The present study details a niobium(V) ethoxide derivative of 8-hydroxyquinoline. The parent compound, niobium(V) ethoxide, Nb(OC 2 H 5 ) 5 is a liquid which reacts with various monofunctional bidentate and bifunctional, tri and tetradentate ligands [15][16][17]. Niobium(V) ethoxide, when reacted with 8-hydroxyquinoline, affords the title compound, whose structure in solution and in solid state is detailed in this study.…”

An 8-hydroxyquinoline derivative of niobium(V) ethoxide was synthesized and characterized by elemental analysis, mass spectrometry, infrared, electronic, and 1 H, 13 C, and 93 NMR spectroscopies. Tetraethoxy(8-quinolinato)niobium(V), as shown by the single crystal structure determination, exists as an octahedral compound in the solid state in which the 8-quinolinato group chelates to the metal atom. In solution, this group partially becomes unidentate; the six-coordinate species is in equilibrium with the five-coordinate species, as shown by 93 Nb and variable-temperature 1 H NMR spectroscopy.
