• 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

• 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)

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)
