# 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.

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:
