The compounds Ge(ONMe2)(4) and Ge(ONEt2)(4) were prepared by the reaction of LiONMe2 and LiONEt2 with GeCl4. They were characterized by H-1 and C-13 NMR and IR spectroscopy, by their decay patterns in the mass spectra, by high-resolution mass spectrometry and by elemental analyses. The crystal structure of Ge(ONMe2)(4) was determined and shows the compound to have a (4+4) coordinate germanium atom as is evident from the Ge-O-N angles, which are in the range between 100.8(3) and 109.2(4)degrees, which is on average 15.2degrees smaller than the Ge-O-C angles in Ge(ONCHMe2)(4). This compound was also prepared and examined by single crystal X-ray crystallography.
