Zincblende

ZnS has a unique structure type compared to other molecules, having different types of unique structures. ZnS can have a zinc blende structure which is a "diamond-type network" and at a different temperature, ZnS can become the wurtzite structure type which has a hexagonal type symmetry. Structure-wise, the zinc blende structure is more thermodynamically favored, however, because of the wurtzite structures slow construction, both forms of ZnS can be found.

ZnS occurs in two common polytypes, zincblende (also called sphalerite) and wurtzite. The two types have these features in common: a 1:1 stoichiometry of Zn:S. a coordination of 4 for each ion (4:4 coordination) tetrahedral coordination.

This model is hand made in the USA by Klinger Educational Products. This is a permanent structure. We only use grade A materials. The 1 inch balls are made of hard Maplewood that includes an enameled painted finish. Polished steel rods are used to connect the wooden balls together.

Zincblende contains 30  -  1 inch balls.
