Simple crystal structures of especial interest
From apm
- Zincblende structure - zincblende ZnS, cubic moissanite SiC, diamond CC, silicon, gernamium, (α-tin aka grey tin SnSn), BN, AlN, ...
- Wurtzite structure - wurtzite ZnS, hexagonal moissanie SiC, lonsdaleite CC (hexagonal diamond), ... (same as above)
- See: Diamond like compounds
- Rock salt structure – simple cubic – (NaCl rocksalt, MgO periclase, TiO hongquiite, FeO wüstite, NiO bunsenite, ...) - See: Transition metal monoxides
- Rutile structure – (tetragnal with simple unit cell) – Rutile TiO2, Stishovite SiO2, ...
- Hematite structure – (hexahonal) – Leukosapphire Al2O3, Tistarite Ti2O3, and Hematite Fe2O3
- Marcasite structure – (ortorhombic with simple unit cell) – FeS2 Marcasite and FeP2 Zuktamururite
- Perovskite structure – (cubic or ortorhombic near cubic – simple unit cell) – CaTiO3 – Perovskite
- A15_phases – (cubic simple unit cell) – (also known as β-W or Cr3Si structure types) – quite covalent intermetallic compounds – Cr3Si, (Nb3Sn superconductor) – Are there any compounds in this group that do not contain scarce elements?

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