We report the first tris(alkoxide)V(III) complex to bind dinitrogen. Removal of THF from V(OR)3THF furnishes the highly reactive V(OR)3 fragment, which binds dinitrogen to form [V(OR)3]2(μ-N2) in the solid state. Dinitrogen is readily released upon dissolution of the complex. Structural and DFT studies are consistent with significant activation of N2 when bound by the vanadium tris(alkoxide) platform.
