Yes, we missed a trick at Crystallography365 towers not having a bit of a world cup theme running through this month, but it’s never too late to jump on a band wagon (at least for the weekend) eh? So here to kick things off is Germanite:
What does it look like?
What is it?
Germany actually has an element named after it, Germanium. But as the crystal structure of Germanium is the same as diamond, we thought we’d pick something a bit more interesting to write about today (also as suggested by @sonicgu on twitter).
Gemanite, was actually named because of the (relatively) large amount of germanium (purple atoms) found in this mineral. However it is mainly made of copper (the blue atoms) that bond with the sulfur (yellow atoms) in the structure. Germanite is quite a rare mineral, and was discovered in a mine in Namibia. Although it is named for its content of germanium, it is not the mains source of this element for industry (germanium is an important semi-conductor). Most germanium comes from impurities found in galena (lead sulfide).
Where did the structure come from?
