SbF5, lone pairs on F? it act as base?

I have a question about SbF5 as a lewis acid/base. What about all the lone pairs on the F atoms? Couldn't these be donated so that SbF(5) would act as a base? Or is it because of the electronegativity of F that that won't happen?

The Sb has an empty d-orbital while the F lone pairs are tightly held.
