Hi,
You could calculate an anomalous difference map using your current phases and
see whether you see any peaks around the atoms you suspect are Cl, S or P
(although the latter should have a clear tetrahedral geometry, certainly at
your resolution). It all depends of course on the wavelength at which you
collected your data (check Ethan Merritt's site), but again at your resolution
you may very well hit lucky.

Subject: [ccp4bb] Anomalous signal for chlorides
Hello everyone,
I have a good data set to 1.17A that I solved by MR.
I come accross some sites that appear to be chlorides. I was
wondering if they could have some anomalous signal.
I also have a well ordered phosphate and a couple of S from Met´s.
How do I go about probing the signal from these?
Thank you. Best,
