Abstract
The first series of phosphane oxide complexes of germanium(IV) halides have been prepared, including trans-[GeF4(R3PO)2] (R = Me, Et or Ph), trans-[GeCl4(Et3PO)2], fac-[GeCl3(Me3PO)3]2[GeCl6] and cis-[GeX2(Me3PO)4]X2 (X = Cl or Br) and characterised by IR and multinuclear NMR (1H, 19F{1H} and 31P{1H}) spectroscopy. Crystal structures of all the above (except trans-[GeCl4(Et3PO)2]) are described. Remarkably, under mild conditions Me3PO displaces halide ligands from GeX4 (X = Cl, Br) to form the cationic species above. Ph3AsO forms trans-[GeF4(Ph3AsO)2], but reaction of Ph3AsO or Me3AsO with GeCl4 leads to the corresponding R3AsCl2. The complexes [GeF4(MeCN)2], [GeF4(thf)2] and [GeF4(MeOCH2CH2OMe)] are also described and the relative Lewis acidities of GeX4 established.
