Vanadium(III) complexes incorporating the silylamino(disilylamido) ligand [(Me_3Si)N{CH_2CH_2N(SiMe_3)}_2]~(2-)[N{N'}_2]~(2-). Synthesis and crystal structure of the dimeric, non-metallocene vanadium(III) hydride[{V(N{N'}_2)}_2(μ-H)_2]

摘要

Three vanadium(III) complexes incorporating the chelating silylamino(disilylamido) ligand [(Me_3Si)N{CH_2CH_2N-(SiMe_3)}_2]~(2-)([N{N"}_2]~(2-)) have been reported. Addition of Li_2[N{N"}_2] to VCL_3.3THF cleanly yielded the vanadium(III) chloride [{V(N{N"}_2] 1, from which the vanadium(III) hydrocarbyl[V(N{N"}_2){CH(SiMe_3)_2}]~2 could be generated by means of salt metathesis. Hydrogenolysis of 2 under dihydrogen produced the thermally stable, dimeric vanadium(III)hydride[{V(N{N"}_2)}_2(μ0H)_2]3. The solid state structure of 3 was determined.
