Iron—germanium bonds reactions with

Bis(/i,-germyl)iron carbonyl complexes without a metal-metal bond were synthesized by the reaction of Fe(CO)5 with germanium tetrahalides and later by an alternate route involving high temperature reaction of Fe(CO)5 with a bis(halogermyl)iron carbonyl complex. Ferrous chloride is a byproduct of these reactions (equation 32)86-89. 

During a thermal test at 150 °C, the ATR analysis of the ZnDTP surface reaction on an iron-coated germanium crystal indicates a rearrangement of the molecule with the formation of P—0—P bonds. The proposed structure for the thermochemical reaction product, supported by the XPS results collected on the same samples, is given in Chart 1.
