AMoO4 compounds



 Can anyone point me in the direction of any work on the tunstate or
 molybdate compounds. These are a series of materials including
 A=Co,Ni,Mn in the general formula AMoO4. There are several related
 structure types including wulframite,scheelite and CoMoO4 (Smith
 1969). Any suitable parameters for MM, be it LJ-6-12,
 Buckingham (with or without shell model) would be helpful.
 Is anyone else working on these types of compounds?
 Can anyone recall any relevent papers?
 Currently i am tring to reproduce the crystal structures.  I then
 want to conduct some dynamics calculations to determine high temperature
 cation sites and compare the results with  exp. data I have collected.
 ANY relevent thoughts appreciated.
    thanks,
       ANDY
