Silicon has the diamond cubic crystal structure with a lattice parameter of 0.543 nm. The nearest neighbor distance is 0.235 nm. The diamond cubic crystal structure has an fcc lattice with a basis of ...

Pyrite’s cubic symmetry arises from its atomic lattice ... the spatial arrangement and symmetry of atoms within a crystal structure. Each system corresponds to a unique way atoms can align ...

This is essentially what happens on the atomic level in a salt crystal. The cubic shape minimizes the energy of the system, ...

Zinc sulphide exists with two different crystal structures, the cubic zinc blend (top diagram) and the hexagonal Wurtzite (lower diagram). In the zinc blend structure the sulphur ions form an fcc ...
