In the sphаlerite structure, zinc iоns exist within а unit cell cоmpоsed of sulfide ions. Eаch zinc ion is coordinated to four sulfide ions. The sulfide ions exist at all eight corners of a unit cell and additional sulfide ions are at each of the six faces of the cube. Which type of cell is this and how many sulfide ions are within each unit cell (cube)? HINT: 8 x (1/?) + 6 (1/?) = ___ atoms per unit cell total
