Antechamber cannot (currently) handle metal ions. The simplest procedure
is to use antechamber on each of the ligands (separately, and without the
metal), then use LEaP to put everything together. An example of how this can
be done for a copper complex that is similar to your Mn center is given here:

[Ross: I think we should move this onto the current tutorial page, because it
covers things that are not on the current list.]
