Preparation of iron carbonyl complexes of germanium(II) and tin(II) each with a terminal fluorine atom

The reaction of β-diketiminate substituted germanium(II) and tin(II) fluorides (LGeF (1) and LSnF (2)) (L = CH{(CMe)2(2,6-iPr2C6H3N)2}) with diiron nonacarbonyl, Fe2(CO)9 at room temperature, leads to the iron carbonyl complexes of germanium(II) LGeFFe(CO)4 (3) and tin(II) LSnFFe(CO)4 (4), respectively. Compounds 3 and 4 were characterized by elemental analysis, NMR spectroscopy, and mass spectrometry. Furthermore, both complexes (3 and 4) were investigated by X-ray structural analysis which shows that both compounds are monomeric in the solid state containing terminal fluorine atoms.
