A Mössbauer study of the title paramagnetic Fe(O) complex was carried out from 4.2 K to 250 K. The electric field gradient (EFG) tensor was found to be temperature independent in accordance with the well isolated nature of state3A2g. Measurements in an applied magnetic field of 6 T confirmed the paramagnetic nature (S=1) of the complex and showed the EFG tensor to be negative. From the thermal variation of the hyperfine field we determined the spin hamiltonian constant D=14 K and find the g-value to be close to the free electron value. Semi-empirical molecular orbital (MO) calculations were carried out with a modelized molecule of D6h symmetry; results are in good agreement with the experimental values (for both the electronic and magnetic properties).

The 19- and 20-electron complexes [Fe(η6-C6Me6)2]n(n= 1,0) are best synthesized by Na/Hg reduction of [Fe(η6-C6Me6)2]2[PF6–]2; the extremely negative value of the quadrupole splitting for [Fe(η6-C6Me6)2], comparison of Mössbauer parameters of [Fe(η6-C6Me6)2]n+(n= 0,1,2), and the temperature dependence of the quadrupole splitting for [Fe(η6-C6Me6)2]+ indicate high metal character for the antibonding e1* orbital and rhombic distortion of the Jahn–Teller-active FeI complex.
