Synthesis of a homoleptic niobium(V) thiolate complex and the preparation of niobium sulfide via thio "sol-gel" and vapor phase thin-film experiments
Reaction of [Nb(NMe2)(5)] with 10 equiv of 2,6-Me2C6H3SH in toluene results in the formation of red crystals of [Nb(SC6H3Me2-2,6)(5)]. Crystal structure analysis of [Nb(SC6H3Me2-2,6)(5)] showed that the niobium center adopts a distorted trigonal bipyramical geometry. Niobium disulfide, NbS2, has been successfully prepared via a thio "sol-gel" process using [Nb(SC6H3Me2-2,6)(5)] as the metal source. In contrast, vapor phase thin-film studies revealed that [Nb(SC6H3Me2-2,6)(5)] functions as a single-source precursor to NbS films.
