Dear Jinyu, Are you sure you have AlF3? I mean, when you prepare your mixture to get AlF3 actually you produce AlF3 and AlF4 (Goldstein, 1964). Indeed depending on the initial concentration of F ion you used you may have a 50% of AlF3 and 50% of AlF4, and any of them could be bound to your protein. I cannot say from the image you sent but at certain resolutions it is easier to notice the difference due to geometry and F - Al distances.
