4,7-Diaza-1-azoniacyclo­nonane bromide

The title compound, C(6)H(16)N(3) (+)·Br(−), is the bromide of the monoprotonated aza­macrocyclic triamine 1,4,7-triaza­cyclo­nonane (tacn). The threefold axis of the triamine is broken by the protonation of one of the three amine functions. The ammonium proton is bonded in an intra­molecular symmet...

Sumario:The title compound, C(6)H(16)N(3) (+)·Br(−), is the bromide of the monoprotonated aza­macrocyclic triamine 1,4,7-triaza­cyclo­nonane (tacn). The threefold axis of the triamine is broken by the protonation of one of the three amine functions. The ammonium proton is bonded in an intra­molecular symmetrically bifurcated hydrogen bond to the two endodentate amine functions. Direct cation–anion contacts are established via N—H⋯Br hydrogen bonds between the bromide anions and tacnH(+) cations.
