摘要：

The hydridosilyl complexes Fe(CO)2(dppe)(H)[Si(OR)3](R = Me, Et) and Fe(CO)(dppe)H3[Si(OEt)3](dppe = Ph2PCH2CH2PPh2) were deprotonated with KH/18-crown-6 to give the anionic silyl complexes [K(18-crown-6)][Fe(CO)2(dppe){Si(OR)3}] (2) and [K(18-crown-6)] [Fe(CO)(dppe)H2{Si(OEt)3}] (4), respectively. Reaction of 2 with Me3ECl (E = Sn or Pb) affords the octahedral complexes Fe(CO)2(dppe)(EMe3)[Si(OR)3] with trans-CO ligands. From 4 and Me3ECl the complexes Fe(CO)(dppe)H2(EMe3)[Si(OEt)3] are formed. Spectroscopic data suggest that those complexes have a capped octahedral geometry, in which the dppe ligand, ER3 and CO are in plane, one hydride ligand is in an axial position and the other hydride caps a triangular face.
