Neutral, monomeric trihaloniobium alkyne complexes of the general formula LnX3Nb(RC≡CR′) (X = Cl, Br L = dimethoxyethane (DME, n = 1); X = Cl, L = tetrahydrofuran (THF, n = 2)) are conveniently prepared from the reaction of NbX3(DME) with alkynes. An X-ray crystal structure of (THF)2Cl3Nb-(PhC≡CSi(t-Bu)Me2) was obtained and indicates that the alkyne unit is bound to niobium in a highly symmetric fashion with identical niobium-carbon distances (2.067 (2) ?). The synthesis of NbBr3(DME) is reported.
