# Replicating an illustration for the crystal structure of ferrihydrite

I came across this image of crystal structure in an article The Structure of Ferrihydrite, a Nanocrystalline Material [1]:

Does someone know the software in which it was produced? I have been looking for a way to visualize crystal structures of some minerals but I am stuck looking for a piece of software capable of doing it. I am aware of Jmol, but it does not show crystal structures too well.

I think the software used could be Diamond (http://www.crystalimpact.com/diamond/)

• Hi and welcome to chemistry.stackexchange.com. Feel free to take a tour. For remaining questions about the site, visit the help center. It would be nice, if you could elaborate a little why the software you suggested is a good choice for OP’s problem. We generally prefer elaborate answers where possible. Other than that, I hope you enjoy your stay =) – Jan Nov 13 '15 at 20:39
• @Jan Thank you for your comment. I was just answering OP's question about the software used to produce that image, so I thought no more details were needed – Zamu Nov 14 '15 at 18:11
• Which is why I didn’t downvote (it looks like it’s good) but merely mentioned ;) – Jan Nov 14 '15 at 18:15

Free (as in beer) alternative to Diamond, Olex2 (works on Windows, Linux and MacOS), can also be used to replicate this structure (I used COD-9011573 CIF). Various bonds for cubane $$\ce{Fe4O4}$$ core, transparent polyhedra and custom coloring schemes are available out of the box:

There is also an extension DrawPlus available on a subscription basis which adds some bells and whistles alongside with extra convenient tools for visualization (though I never used it myself).
