Inorganic rings of various types can be formed as a result of the broad range of bond types available. Cyclic structures formed by self-assembly of molecular building units (tectons) are discussed in terms of supramolecular chemistry concepts. The formation of covalent rings can be understood in terms of combining various fragments (synthons) in which the central atoms can display various oxidation states, coordination numbers, and geometries, leading to a broad structural diversity of cyclic structures for a given composition of the ring skeleton (as illustrated for P2N2 and Si2N2 rings).
