Have a look at


Next to that, also consider that you are talking about a site with -2
formal charge (ZnS4)2-. How likely is that? From QM studies, it seems
much more likely that there are 1 or 2 protons associated with the
cluster. If you manage to model that properly, let me know; I'd be
interested in that.
