Gittercomplex (Ge).
Definition
A lattice complex is the set of all point configurations that may be generated within one type of Wyckoff set.
The name lattice complex comes from the fact that an assemblage of points that are equivalent with respect to a group of symmetry operations including lattice tranlations can be visualized as a set of equivalent lattices.
History
Paul Niggli introduced in 1919 the term lattice complex to indicate a set of crystallographically equivalent atoms in a crystal structure, like the Na atoms in NaCl or the C atoms in diamond.
