Often coordinated to a central ligand, the nitrogens occupy the vertices of a tetrahedron, with potentially four faces and six edges, with the carbon chains running approximately along the edges. They can have a "bowl" or "cage" structure, with varying lengths or omission of the carbon chains. In the nomenclature of Springborg et al. (1996) these can be described according to the number of chains of specified length: thus, for example, [14.22]adamanzane is 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane, a compound which contains four one-carbon chains and two two-carbon chains linking the nitrogen atoms.
