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

Abstract

The reaction of β-diketiminate substituted germanium(II) and tin(II) fluorides (LGeF ( 1) and LSnF ( 2)) (L = CH{(CMe) 2(2,6- iPr 2C 6H 3N) 2}) with diiron nonacarbonyl, Fe 2(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.
