All known inhibitors can be subdivided into several groups according to certain analytical criteria. Mostly, inhibitors are sorted by their chemical nature or by specificity regarding to certain polymerases and polymerase families. 

In order to have around each atom in this hexagonal structure four exactly equidistant neighbouring atoms, the axial ratio should have the ideal value (8/3 that is 1.633. The experimental values range from 1.59 to 1.66. This practical constancy of the axial ratio, in contrast with what is observed for other families of isostructural compounds such as those of the NiAs type, may be attributed to a sort of rigidity of the tetrahedral (sp3) chemical bonds. As for the atomic positional parameters, the ideal value of one of the parameters (being the other one fixed at zero by conventionally shifting the origin of the cell) is z = 3/8 = 0.3750. The C diamond, sphalerite- and wurtzite-type structures are well-known examples of the normal tetrahedral structures (see 3.9.2.2). 

The Mendeleev Periodic Ihble represents a kind of compass in chemistry. Instead of having a sort of wilderness, where all the elements exhibit their unique physical and chemical properties as deus ex machina, we obtain understanding that the animals are in a zoo, and are not unrelated, that there are some families, which follow from similar structure and occupancy of the outer electronic shells. Moreover, it became clear that there are cages in the zoo waiting for animals yet to be discovered. The animals could have been described in detail before they were actually found by ejqjeriment. This periodidly pertains not only to the chemical and physical properties of elements, but also to all parameters that appear in theory and are related to atoms, molecules and crystals.
