Hi Robbie,
Have you looked at the anomalous difference Patterson to check for peaks? I
recently solved a structure at only 2.8 A resolution using the Br peak data
(SHELX-D was necessary for finding the initial phasing sites (10 out of
>40). Thus, assuming your anomalous differences are real, 1.8 A should be
more than sufficient to solve your structure. I suggest trying RSPS or
SHELX-S (or SHELX-D if you have a large unit cell with a lot of Br sites) to
locate them.
Good luck!
