摘要：

Depending on the nature of the central metal and experimental conditions, the reaction of dihydride MH2P4 [M = Fe, Ru, Os; P = P(OEt)(3), PPh(OEt)(2)] with SnCl2 gives both hydride-trichlorostannyl- MH(SnCl3)P-4 (1,2) and bis(trichlorostannyl) complexes M(SnCl3)(2)P-4 (3, 4). Treatment of compounds 1-4 with NaBH4 in ethanol yielded both mono(trihydridestannyl) MH(SnH3)P-4 (5, 6) and bis(trihydridestannyl) derivatives M(SnH3)(2)P-4 (7, 8). Reaction of the hydride-trihydridestannyl complexes MH(SnH3)P-4 with CO2 (1 atm) led to hydroxobis(formate)stannyl derivatives MH[Sn-(OH){OC(H)=O}(2)]P-4 (9, 10). The complexes were characterized by spectroscopy (IR and H-1, P-31, C-13, Sn-119 NMR) and by X-ray crystal structure determination of OsH[Sn(OH){OC(H)=O}(2)][PPh-(OEt)(2)](4) (10b).
