The solid and solution state structure of the vanadium(ii) N-heterocyclic silylene (NHSi) complex, [(IPr)V(Cp)] (1) is reported (IPr: 1,3-bis(2,6-diisopropylphenyl)-1,3-diaza-2-silacyclopent-4-en-2-ylidene). The electronic structure of 1 is probed using a combination of magnetic measurements, EPR spectroscopy and computational studies. The V-Si bond strength and complex forming mechanism between vanadocene and an NHSi ligand is elucidated using computational methods.
