摘要：

Two vanadium(iii) complexes, Cz(tBu)(Pyr(iPr))(2)VCl2 (1) and Cz(tBu)(Pyr(iPr))(2)V(N-3)(2) (2), were synthesized and characterized. Chemical reduction of both 1 and 2 gives the thermally stable nitrido-bridged vanadium(iv) dimer complex, [{Cz(tBu)(Pyr(iPr))(2)}V](2)(mu-N)(2) (3), which is a rare example of a dimeric vanadium(iv) complex bridged by two nitrido ligands. The nitride ligands of 3 are unreactive due to the well-protected environment provided by the pincer ligand and its substituents, as is supported by its X-ray crystal structure and further described by DFT calculations.
