The interpretation of heterometallic bonding nature is a basic work of inorganic chemistry.By means of intermetallic substitution of germylene anions with iron halide complexes CpFe(CO)2I and β-diketiminato FeⅡ chloride,the ferrogermylene complexes 3a,3b and 4a were synthesized and structurally charac-terized.The structural and IR characterizations show the presence of the Ge←Fe π backbonding in molecules 3a,3b and 4a.The computational works on frontier molecular orbitals and their compari-son of energy states confirmed that σ donation and π backbonding are both weak in these molecules,despite three complexes have longer Ge-Fe bonds,whose strength decreases slightly with the degressive electron density around Fe environment in a sequence from 3a,3b to 4a.
