Nanostructures with coherent boundaries are considered in the framework of the local approach.It is demonstrated that the use of the fiber space formalism makes it possible to derive a set of geometrical structural complexes that are building blocks of nanostructures.These complexes are determined by the specific sub-configurations of finite projective planes.It is shown that,in the case of fourfold-coordinated structures,crystalline and quasicrystalline fragments can intergrow coherently (without dangling bonds).
