The crystal structure is a member of the hexagonal crystal system and consists of tetrahedrally coordinated Zinc and Sulfur atoms that are stacked in an ABABAB pattern.
The structure is closely related to the structure of lonsdaleite, or hexagonal diamond.
As there all orientations of the crystal, rings of different 2θ values are formed
