Abstract
Combined interpretation of electron diffraction and spectroscopic data for the CeF4 molecule is reported. It is shown that the diffraction pattern corresponds to a tetrahedral structure of the molecule with the following effective configuration parameters (T=1180(50) K): rg(Ce-F)=2.036(5) Å, rg(F-F)=3.312(25) Å, l(Ce-F)=0.074(3) Å, l(F-F)=0.261(17) Å. The total force field of the CeF4 molecule is found in a harmonic approximation. Possible participation of the Ce f-electrons in chemical bonding is discussed.
