T.D.Tilley's molecular precursors may be a good model of the local 
environment around the molybdenum (Chem. Mater. 2005, 17(7), 1818-1828). 
  I don't remember if he gives a crystal structure for his 
Moly-silicates, but it's a starting place.  If you can find the crystal 
structure for a moly-silicate, you should be able to build a decent 
model using a blank Atoms template.
