Ge12{Fe(CO)3}8(μ-I)4: a germanium–iron cluster with Ge4, Ge2 and Ge units

Author affiliations

Abstract

The germanium–iron cluster Ge12{Fe(CO)3}8(μ-I)4 was prepared by reacting GeI4 and Fe2(CO)9 in [BMIm]Cl/AlCl3 as ionic liquid (BMIm: 1-butyl-3-methylimidazolium). The cluster contains a Ge12Fe8 metal core consisting of a central Ge4 rectangle, two Ge2 pairs, and four single Ge atoms. These Ge units are interconnected by Fe atoms to a real Ge–Fe cluster. According to DFT calculations, Hund's localization criterion is fulfilled for the whole cluster if we assume three different atomic charges on the Ge4, Ge2, and Ge units.
