Abstract

Abstract The one-electron oxidation of NbCp 2′H 3, 1 (Cp′ = Me 3SiC 5H 4), has been found to give the dimeric niobium(IV) complex (NbCp 2′H 2) 2, 3, which has been characterized by ESR spectroscopy. The cationic niobium(V) species [NbCp 2′H 2(THF)] +, 4, has been prepared through a two-electron oxidation of 1. 3 can also be obtained by one-electron reduction of 4. The same behaviour has been observed for Nb(η 5- tBuC 5H 4) 2H 3.
