1,6-Diazabicyclo[4.4.4]tetradecane and its lnside-protonated lon: Changes in Space Groups

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 R3c and (2) in P31c; both moieties have crystallographically imposed point symmetry D_3 rather than C_2
