Image of crystal structure

Is there any websites or resources where I can get a good image of a certain crystal structure? In my case I'm looking for lead(II) tungstate $\ce{PbWO4}$ and I can't find a vivid graphic on google (except of the structural formula).


I've seen [modeling structure of crystals](https://chemistry.stackexchange.com/questions/40637/modeling-structure-of-crystals), but unfortunately the software is commercial.




I recommend to fetch the crystal structures of inorganic compounds via specific Google search pattern `site:crystallography.net <keyword(s)>`, e.g. in your case


`site:crystallography.net PbWO4`


yields in [this COD page](http://www.crystallography.net/cod/9015950.html) where you can use JSmol to do basic visualization right in your web browser. Alternatively, you can [download CIF](http://www.crystallography.net/cod/9015950.cif) and work further offline with numerous free tools such as [Mercury](https://www.ccdc.cam.ac.uk/solutions/csd-system/components/mercury/) or [Olex2](http://www.olexsys.org/). Both are free and available for Windows, Linux and MacOS.

I follow a similar methods as mentioned above. First, locate the CIF file as described above.


I use [VESTA](http://jp-minerals.org/vesta/en/) which is a free, multiplatform molecular visualization program. Its relatively easy to get a decent image out of it (File>Export Raster Image):

You can even render vector images! You have relatively little control over the style of the image, but it works well for basic images. I usually only find myself tweaking the shininess of the atoms and bonds(Objects>properties>Atoms).
