The crystal structure of the ytterbium hexameric cluster in CaF{sub 2} has been calculated in the framework of the embedded--cluster method within the shell model, in pair potential approximation. The crystal field parameters and scheme of the energy levels for Yb{sub 6}F{sub 36} hexameric cluster were calculated in the exchange charges model. Also, the optical spectra of Yb{sup 3+} single center in CaF{sub 2}(cubic and tetragonal symmetry) was calculated and discussed.
