摘要：

The complexes FeH3(PPh2R')3ER3 (R' = nBu: ER3 = SnPh3, SiMePh2; R' = Et: ER3 = SnPh3) were prepared by reaction of Fe(H)2(H2)(PPh2R')3 with HSnPn3 or HSiMePh2. The heavy-atom skeleton of FeH3(PPh2Et)3SnPh3 shows an approximate C3 symmetry in the crystalline state and a nearly tetrahedral FeP3Sn core. However, the NMR spectra indicate the presence of Fe,H,Si(Sn) three-center two-electron bonds at low temperature in solution.
