Abstract
Diamondoid structures with shared vertices, edges, or 6-membered rings can theoretically be
curved into toroidal structures whose calculated energy provides information about steric strain.
Diamondoid hydrocarbons sharing one vertex between two adamantane units are called [n]spiromantanes,
where n indicates the number of adamantane units. When a pair of adamantane units shares one CC bond,
the resulting assembly is called one-edge-[n]mantane, specifying (by letters in square brackets) which
bonds are shared by the adamantane units. Two adjacent edges may be shared by a pair of adamantane
units, and the assembly is called two-edge-[n]mantane, again specifying by letters in square brackets the
shared bonds. Catamantanes or perimantanes sharing a 6-membered ring of carbon atoms may form larger
rings in an assembly which is called [n]cyclomantane; in the case of catamantanes, the structure of the
diamondoid is specified by codes of the dualists. Finally, nanotubes derived from hexagonal diamond, as
well as corresponding toroidal structures, are discussed.
