A classification of the trigonal prismatic and octahedral structures exhibited by the layered dichalcogenides of group IV B, V B and VI B metals is achieved through consideration of the relative size, polarisation of the bonding orbitals, and the ionicity of the metal-chalcogen bond. A plot of the ratio of the covalent radii of the metal and chalcogen atoms against Pauling's resonating bond ionicity is shown to successfully achieve a separation of the two structures, consistent with the primarily covalent nature of the bonds. © 1975.
