complex (3) showed a modulated behavior: at room temperature, (3) still slowly eliminates mainly chlorotrimethylsilane with the formation of [(i-PrO)2P(NSiMe3)2]GeCl (6). Structure of this chlorinated germanium(II) compound which can also be seen as a germyl anion has been evidenced by an X-ray analysis. But at higher temperature (40–50 °C) (3) mainly decomposes with elimination of isopropylchloride leading
