Summary:In order to understand the origin of polytypism observed in the ZnS structure, a new model is proposed in this letter which is based on bonding modulation and the Coulomb interaction of the resulting charge-density modulation. The bonding conformation along the stacking direction consists of two types of bonding in sixmembered rings, namely the boat and chair conformations. These rings have different bond lengths. Polytypes are a periodic mixture of these two conformations, so that the bondlength modulation results in a long periodic charge-density modulation.
