Abstract

The dihydride-dichloro complex OsH2Cl2-(P iPr3)2 (1) reacts with 4.0 equiv of HSnPh 3 to afford 2.0 equiv of ClSnPh3 and the tetrahydride-bis(stannyl)-osmium(VI) derivative OsH4(SnPh 3)2(PiPr3)2 (2), which has been characterized by X-ray diffraction analysis. DFT calculations in a model system of 2, in which the bulky ligands have been replaced by small models, followed by QM/MM optimizations with the real ligands have allowed the complete determination of the hydride positions and the role played by the steric effects on the experimental structure.
