habits of coordinational polyhedras are considered as forms of nanocrystals. Habits for coordination polyhedra with numbers from 1 to 30 are given. It was analazide the cubic and hexagonal lattices. There are the next nanocrystals: primitive, cubic and intercentered and face-centered and diamond-like (all cubic) and hexagonal close packed.

The points on off reciprocal lattice with equal radii-vector have been named as crystallographic cluster (CC). The position of CC does not depend on the choice off unit cell in crystals lattice. But their indices of CC are distinguished for different unit cell in the same crystal. As an example it was analysis the CC of two hexagonal unit cell with γ = 1200 and γ = 600.
