The crystal structures of 1,6-diazabicyclo[4.4.4]tetradecane (1) and of its inside-protonated ion (2), which were originally described in space group C2/c, should be described instead in trigonal space groups, (1) in R![[3 with combining macron]](http://www.rsc.org/images/entities/char_0033_0304.gif)
c and (2) in Pc; both moieties have crystallographically imposed point symmetry D3 rather than C2.
