Abstract:
Heteronuclear Group 3 metal/iron carbonyl anion complexes ScFe(CO)3 - , YFe(CO)3 - , and LaFe(CO)3 - are prepared in the gas phase and studied by mass-selective infrared (IR) photodissociation spectroscopy as well as quantum-chemical calculations. All three anion complexes are characterized to have a metal-metal-bonded C3v equilibrium geometry with all three carbonyl ligands bonded to the iron center and a closed-shell singlet electronic ground state. Bonding analyses reveal that there are multiple bonding interactions between the bare group-3 elements and the Fe(CO)3 - fragment. Besides one covalent electron-sharing metal-metal σ bond and two dative π bonds from Fe to the Group 3 metal, there is additional multicenter covalent bonding with the Group 3 atom bonded to Fe and the carbon atoms.
