Abstract
Combined interpretation of electron diffraction and spectroscopic data for the CeF4 molecule is reported. It is shown that the diffraction p attern correspond; to a tetrahedral structure of the molecule with the following effective configuration parameters (T = 1180(50) K): r(g)(C e-F) = 2.036(5) Angstrom, r(g)(F-F) = 3.312(25) Angstrom, l(Ce-F) = 0. 074(3) Angstrom, l(F-F) = 0.261(17) Angstrom. The total force field of the CeF4 molecule is found in a harmonic approximation. Possible part icipation of the Ce f-electrons in chemical bonding is discussed.
