Abstract
The molecular structure of the 2,5-diazabicyclo[2.2.1]heptane parent ring has been characterized for the first time. The asymmetric unit contains two crystallographically independent cages of 2,5-diazabicyclo[2.2.1]heptane, each cage being protonated at the two nitrogen sites. The overall charge balance is maintained by four crystallogrphically independent bromide ions. In the crystal, the components of the structure are linked via a complex three-dimensional network of N—H⋯Br hydrogen bonds.
