在双膦和 N2 存在下，VCl3(thf)3(thf = 四氢呋喃) 被 Na 还原，生成配合物反式-[V(N2)2L2]–，其结构已通过 X 射线晶体学表征为 L = Ph2PCH2CH2PPh2，并在溶液中通过 51V NMR 光谱表征为 L = Me2PCH2CH2PMe2； 25%的配位N2被HBr还原质子化为NH3和少量N2H4。
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.
