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

The reaction of beta-diketiminate substituted germanium(II) and tin(II) fluorides (LGeF (1) and LSnF (2)) (L = CH{(CMe)(2)(2 6-iPr(2)C(6)H(3)N)(2)}) with duron 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 (C) 2010 Elsevier BV All rights reserved
