If you place a sulphate and it refines in a sensible way - temperature
factors for the group more or less agreeing that is good.
Is there a decent set of H bonds?
Was there sulphate available in the medium?

is there a anom peak marking the S position - but you need good data to
hope to find this - you can verify quality by checking all other S in
the crystal
