Phosphine complexes of main group elements. [(Me3Si)C(PMe2)2]2Ge2I2, and intramolecular germylene (germanediyl) donor–germylene acceptor complex with a germylene–phosphane chelating ligand

Abstract

The addition of I₂ to the bis-germylene complex [(Me₃Si)C(PMe₂)₂]₂Ge₂(Ge^I–Ge^I)(1) surprisingly results in the oxidation of only one Ge atom and rearrangement of one of the phosphinomethanide ligands; the Gel₂ formed is complexed by a chelating germylene–phosphine ligand in the form of a homonuclear donor–acceptor complex.
