• Wurtzite
• Structure distortion
• Empirical models
• Bond valence model

The wurtzite-type ionic compounds exhibit flattened tetrahedral sites with a decentering of the central atom. The tetrahedral distortion and the relationship between the atom parameter (z) and the c/a ratio were explained on the basis of cell volume optimization respecting the bond valence model, and the role of anharmonic atomic vibrations was emphasized.
