- Pyrite structure – FeS2 pyrite, NiS2 vaesite, MnS2 hauerite
- Quartz structure
Cubic but very big unit cell
- Spinel structure – 3D structure (mineralienatlas)

- Bixbyte structure – 3D structure (mineralienatlas)
Special cases (related to concrete and calcium aluminates):
- Compound: Dodecacalcium_hepta-aluminate
- Mineral: Chlormayenite
Side-notes
The 3D voroni cells around the atoms can be used to gain sets of space-filling
polyhedral shapes for polyhedral microcomponents on a much larger scale.
(It's not Wiegner Seiz cells, this would bbe arround lattice points rather than atoms)
