摘要：

We report the synthesis of heteroleptic iron complexes supported by both a bis-phosphine ligand (depe) and a bis-NHC ligand. The mixed ligand sets provide access to iron (0) adducts of N2 and CO that are highly activated, in comparison to homoleptic (i.e. Fe(depe)2L) variants. Computational and experimental studies revealed the mixed ligand set distorts the geometric and electronic structure to yield an unusually basic iron. Although protonation occurred at Fe, silylation of the Fe(0)N2 complex afforded a highly activated silyldiazenido [FeNNSiMe3]+ complex.
