Abstract

Chemical modification of niobium pentaethoxide (Nb(OCH₂CH ₃)₅; Nb(OEt)₅) with catechol (C ₆H₄OH)₂; H₂cat) was investigated using infrared spectroscopy, ¹H and ¹³C nuclear magnetic resonance spectroscopy, compositional analysis and mass spectrometry. Niobium pentaethoxide was chemically modified with catechol by the formation of catecholate groups (cat^2-) bound to niobium, and a corresponding release of ethanol was observed. The obtained product was [(cat)Nb(OEt) ₃]_n, which included the dimmer [(cat)Nb(OEt) ₃]₂.
