The hexagonal crystal family is one of the seven crystal systems in crystallography, characterized by a specific arrangement of atoms within a crystal lattice. In the hexagonal system, crystals have a three-dimensional structure defined by three axes of equal length that intersect at angles of 120 degrees in one plane (the basal plane) and a fourth axis that is perpendicular to this plane.
