You need a force field that is parameterized for metalloclusters. I am 
not aware that there is a "standard" force field for such things - 
certainly none/few of the biomolecular MM force fields will be suitable. 
Check the literature for MD simulations of metalloclusters to see what 
they do, and adapt that to your needs.
