Resumen

Pentafluorophenyl derivatives of chromium (III) containing the tetradentate ligand N,N' ethylenebis(salicylaldiminate) (2—) (salen) has been preparad by the reaction between ClCr(salen)py and the Grignard reagent and further addition of the appropriate ligand: THF, dioxane (Dx), H2O, py, and OPPh3. The pentacoordinate species C6F5Cr (salen) is obtained by thermal heating of C6F5Cr (salen) Dx. Structural data for these organocomplexes are obtained by V-UV and IR spectroscopy and magnetic susceptibility measurements.
