Chalcopyrite Wikipedia

Chalcopyrite is a member of the tetragonal crystal system. Crystallographically the structure of chalcopyrite is closely related to that of zinc blende ZnS ().The unit cell is twice as large, reflecting an alternation of Cu + and Fe 3+ ions replacing Zn 2+ ions in adjacent cells. In contrast to the pyrite structure chalcopyrite has single S 2− sulfide anions rather than disulfide pairs.
