The wurtzite structure is also known as the α-ZnS structure. One way to understand it is to consider it as a hexagonal close packed array of anions, with half the tetrahedral interstices filled by cations.

Every anion is surrounded by four cations and has tetrahedral coordination geometry. Likewise, every cation is tetrahedrally coordinated by four anions.

Many compounds adopt the wurtzite structure, including w-BN, β-AgI, ZnO, BeO, AlN, α-CdS and CdSe.
