Formatted abstract
The report of the synthesis of the complex [(1,3,6,8,10,13,16,19-octaazabicyclo[6.6.6]icosane)cobalt(III)] chloride ([Co(sep)]Cl3) in 1977 was innocuously titled “A macrobicyclic nitrogen cage for metal ions”. The short, two page, manuscript reported the assembly of an encapsulating ligand through a series of small ring closures around the ubiquitous [Co(en)3]3+ ion, resulting in the ready isolation of the complex of the octaazacryptate termed « sepulchrate » (sep). The scope of this seemingly simple chemistry, and the extension of it over the past four decades, was prophesied in this first paper. Herein, we review the extensions of this chemistry, from the basic coordination chemistry to practical applications, and illustrate the fact that apparently simple chemistry can lead to diverse and in many ways revolutionary outcomes.
