Look at AMBERHOME/dat/leap/lib/atomic_ions.lib. Copy one of the
monatomic ions there, and give it a new name, and new atom type. Adjust
the charge to -5. Then create a frcmod file (see examples in the
../parm folder), to assign a mass and non-bonded parameters to the new
atom type you created.
....good luck...dac
