===Five-membered rings with ''two'' heteroatoms===
The 5-membered ring compounds containing ''two'' heteroatoms, at least one of which is nitrogen, are collectively called the azoles. Thiazoles and isothiazoles contain a sulfur and a nitrogen atom in the ring.  Dithiolanes have two sulfur atoms.

===Five-membered rings with at least ''three'' heteroatoms===
A large group of 5-membered ring compounds with ''three'' or more heteroatoms also exists. One example is the class of dithiazoles, which contain two sulfur atoms and one nitrogen atom.

===Six-membered rings with six heteroatoms===
The hypothetical chemical compound with six nitrogen heteroatoms would be hexazine.
 
Borazine is a six-membered ring with three nitrogen heteroatoms and three boron heteroatoms.
 
== 7-membered rings ==
In a 7-membered ring, the heteroatom must be able to provide an empty π-orbital (e.g. boron) for "normal" aromatic stabilization to be available; otherwise, homoaromaticity may be possible. Compounds with one heteroatom include:
