CCL: suggestions needed.....



Dear CCL users.
   Thank you for your valuable time.
   I am working on organometallic Compounds containing 6 carbon atoms with a Metal atom Pt, Re, pd.
   Now i am planning to optimize them geometrically.
   I am also looking forward to continue my work focusing the development of forcefields that which can explicitly  to treat Metal atoms (like Pt, Pd, Os, Re, Ru, Fe) containing Organic compounds.
  So i kindly request all the computational chemistry experts. please suggest me how to start from scratch  for the development of the forcefield for specially Metal atom containing Organic Compounds.

I also kindly request you to post me some links or some references literature.
This is very helpful to me.

Excuse me for my bad english.
Thank you in advance.


Regards
Walden
