Synthesis and structure of 1,1'-bis(pentafluorophenyl)tetrahydrodigermane

Article abstract of DOI:10.1007/BF00695834

Dehydrogenation of pentafluorophenylgermane in the presence of catalytic amounts of a Wilkinson complex, certain Rh^I ortho-benzosemiquinolate complexes, or (Ph3P)4Pt leads to tetrahydrodigermane, C6F5H2GeGeH2C6H5.X-ray analysis has confirmed the trans-arrangement of the C6F5-cycles at the Ge atoms.The Ge-Ge bond length is 2.394(1) Angstroem.The doublet pattern of the band due to the Ge-H bonds (ν 2090 and 2104 cm^-1) in the IR spectrum is probably associated with nonequivalence of the hydrogen atoms in the molecule. - Key words: synthesis; 1,1'-bis(pentafluorophenyl)tetrahydrosigermane; X-ray analysis.
