Controlled synthesis of nano-alloys of iron germanide has gained a renewed interest thanks to the recent discovery of new applications in the field of information storage. However, the chemistry of the iron-germanium pair is a complex chemistry that remains little studied. The work presented in this thesis combines molecular chemistry and nano-object chemistry to explore the potential of single-source precursors for solution synthesis, in soft conditions, of iron germanium NPs. First, we focused on the formation of new complexes with an amidinatogermylene-type architecture offering a balance between the stabilization of complexes and their decomposition temperatures, for example mono-germylene iron complexes {[iPrNC(tBu)NiPr]GeCl}Fe(CO)4 and {[iPrNC(tBu)NiPr]GeHMDS}Fe(CO)4 or the bis-germylene iron complex {[iPrNC(tBu)NiPr]GeCl}2Fe(CO)3. In a second step, we show that this method represents a path of choice to reach the formation of nano-alloys of iron germanide and that the architecture of the mono-source precursors allows to control the final nanoparticles. In particular, the decomposition at 200°C. of the {[iPrNC(tBu)NiPr]GeHMDS}Fe(CO)4 complex leads to the formation of Fe3,2Ge2 spherical nanoparticles, with a mean diameter of 6.5 ± 0.8 nm, exhibiting a ferromagnetic behavior
