This is a hard proposition to address...

Explanation:

You got #Fe^(2+)# versus #Fe^(3+)#, #d^6# versus #d^5#... Ferric ion SHOULD be more Lewis acidic...and SHOULD give rise to more ionic character. But it is hard to think of a metric that would demonstrate the greater ionic character of ferric ion conclusively. Let us know the answer you get.
