Help regarding V2O5 cell information
 

I want to construct a cell of Vanadium pentoxide for computational study. It belongs to an orthorhombic crystal structure and there is no model existing in Materials studio corresponding to it. There is MoO3 which belongs to the same crystal structure but it has a different stoichiometry. Can anyone tell me how to do it? Is there a place where I can get lattice constants and coordinates of atoms or should I modify MoO3 by deleting an oxygen atom?

Thanks in advance!
