Abstract

The crystal and molecular structures of the fluorocymantrenes [(C5H4F)Mn(CO)(3)] and [(C5H5-nFn)Mn (CO)(2)(PPh3)] (n = 1-3) have been studied. The influence of the phosphine for carbonyl substitution on the bond parameters is larger than the influence of the increasing fluorine content. In most cases the Mn -> P vector is in a transoid position relative to the fluorine substituents, and therefore the conformational parameters of the PPh3 propeller are in these cases very similar. The crystal structures show many intermolecular C-H center dot center dot center dot O hydrogen bonds and only very few C-H center dot center dot center dot F hydrogen bonds. [GRAPHICS]
