  Complex Formation and Rearrangement Reactions of the Phosphine Hydride Anions [OsH₃(PPh₃)₃]^- and [IrH₂(PPh₃)₃]^-

  摘要：

  [OsH4(PPh3)(3)] (1) reacts with KH in THF in the presence of 18-crown-6 to form [K(THF)(18-crown-6)][OsH3(PPh3)(3)] (2), characterized by NMR spectroscopy and X-ray crystallography; cation-anion contact is achieved through three Os-H---K moieties. In contrast, [IrH3(PPh3)(3)] (6) reacts with KH and 18-crown-6 in THF with redistribution of ligands to produce the known bis-phosphine complex [K(18-crown-6)][IrH4(PPh3)(2)] (7). This reaction has been followed by NMR spectroscopy, and [IrH2(PPh3)(3)](-) has been identified as a likely intermediate. K[OsH3(PPh3)(3)] (3) reacts with (Bu3SnCI)-Sn-n to form the tinosmium complex [OsH3(SnBu3n)(PPh3)(3)] (8), characterized by NMR spectroscopy and X-ray crystallography. The molecule contains a seven-coordinate osmium center, which can be described approximately as a distorted fac-[OsH3(PPh3)] arrangement, with the SnBu3n moiety capping the OsH3 face.
