Abstract
Reduction of VCl3(thf)3(thf = tetrahydrofuran) by Na in the presence of bis(phosphines) and N2 yields the complexes trans-[V(N2)2L2]–, which have been structurally characterized by X-ray crystallography for L = Ph2PCH2CH2PPh2, and in solution by 51V NMR spectroscopy for L = Me2PCH2CH2PMe2; 25% of the coordinated N2 is reductively protonated to NH3 and a small amount of N2H4 by HBr.Keywords
