Detailed explanation-1: -Crystal chemistry is the study of the principles of chemistry behind crystals and their use in describing structure-property relations in solids.

Detailed explanation-2: -crystal, any solid material in which the component atoms are arranged in a definite pattern and whose surface regularity reflects its internal symmetry.

Detailed explanation-3: -The crystal structure consists of the same group of atoms, the basis, positioned around each and every lattice point. This group of atoms therefore repeats indefinitely in three dimensions according to the arrangement of one of the Bravais lattices.
