Conclusions

  1. 1.

    The presence of rotational isomerism around the iron-germanium bond in derivatives of cyclopentadienylirondicarbonyl of the type of π-C5H5(CO)2FeGeCl2R (R=CH3, C2H5, n-C3H7 and i-C3H7) and π-C5H5(CO)2FeGeX2CH3 (X=Cl, Br, I) was demonstrated by the method of IR spectroscopy.

     
  2. 2.

    The enthalpy differences of the rotational isomers (ΔH) were calculated, and their dependence on the nature of the substituents R and X at the germanium atom is discussed.

     
  3. 3.

    The dependence of ΔH on the dielectric permeability of the solvent and an estimation of the dipole moments show that for all the compounds studied, the less polar trans-isomer is more stable.
