The ferriogermylenes ArGeFeCp(CO)2(Ar = −C6H3-(C6H2-2,4,6-Me3)2(ArMe6(1a)), Ar = −C6H3-(C6H3-2,6-iPr2)2(AriPr4(1b))) (Cp = η5-C5H5) react with an excess of NH3(l) to form the insertion products ArGe(NH2)(H)FeCp(CO)2(Ar = ArMe6(2a) or AriPr4(2b)). Similarly, ferriogermylene 1areacts with water to form the insertion product ArMe6Ge(OH)(H)FeCp(CO)2(3). Unusually, crystals of 1aexist as three different polymorphs whose structures differ primarily in their Cipso–Ge–Fe bond angles. Complexes 1–3were characterized by NMR, UV–vis, IR spectroscopy, and X-ray crystallography. |
