modelling of inorganic crystals



dear all,
 i am looking for references for:
 - model potentials and forcefield parameters for
   (classical) modelling of inorganic salts
 - (possibly review) articles about the derivation
   and the theoretical background of such forcefields
 - ways to get (transferable??) parameters via theoretical
   calculations rather than empirical fitting
 thank you in advance for any hints!
 cheers
 Michael
