If I understand you, you got an optimized geometry & a MEP in these QM
conditions and then you fitted the charges using the
Merz-Singh-Kollman scheme in turbomole.

TIP3P is for water; the types of your hydrogens in your metal complex
should be HC, H1, H2 if you use parm99...
Did you use "verbosity 2" in LEaP? What error messages do you get
(besides the one your reported previously)?
Difficult to help without more information... If you wish you can send
me your LEaP job (with leap.log, FF library & PDB file) so that I can
have a look.
regards, Francois
