One doesn't draw a (single) Lewis structure for what is clearly 2 if not 3 ions ... I am guessing you've got Fe2+ (Fe3+ leads to an oxidation number of +4 for Sb which wouldn't be right). The problem of drawing a Lewis structure for Sb2O74- should be easier for you than trying to include Fe atoms as well.

The corresponding biphosphate P2O74- should be possible to find. Stibium looks siimilar.
