Abstract: Cyclophane and linear phane systems are considered as parent hydrides. Their derivatives are named in conformity with the principles, rules and conventions prescribed for naming organic compounds. The following nomenclatural features are described: indicated and added hydrogen, order of seniority for numbering, substituents expressed as suffixes, substituents cited as prefixes, phane parent hydrides modified by addition or subtraction of hydrogen atoms, and polyfunctional derivatives.
