- Zincblende structure - zincblende ZnS, cubic moissanite SiC, diamond CC, silicon, gernamium, (α-tin aka grey tin SnSn), ...
- Wurtzite structure - wurtzite ZnS, hexagonal moissanie SiC, lonsdaleite CC (hexagonal diamond), ... (same as above)
- See: Diamond like compounds
- Rock salt structure - simple cubic - (NaCl, MgO) - See: Transition metal monoxides
- Rutile structure - (tetragnal with simple unit cell) - Rutile TiO2, Stishovite SiO2, ...
- Hematite structure - Leukosapphire Al2O3, Tistarite Ti2O3,
- Marcasite structure - (ortorhombic with simple unit cell) - FeS2 Marcasite and FeP2 Zuktamururite
- Perovskite structure - (cubic or ortorhombic near cubic - simple unit cell)
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)
