A [[crystal structure]] is composed by a finite number N of [[crystallographic orbit]]s. When N > 1, a subset N’ (1 ≤ N’ < N) of the [[crystallographic orbit]]s of S defines a '''substructure'''.

In chemistry and material science literature a substructure is often but incorrectly called a [[sublattice]]. A [[lattice]] is a mathematical description of the periodicity of a crystal structure and does not possess atomic nature. Furthermore, the translation lattice built on the subset of atoms defining a substructure can either coincide with the lattice of the original structure or be a [[superlattice]] of it, but never a sublattice.
