Abstract
The X-ray structure determinations of the two title compounds, namely 7-methyl-7,17-diaza-3,11-diazoniabicyclo[11.3.1]heptadeca-1(17),13,15-triene dichloride monohydrate, C14H26N42+·2Cl−·H2O, (I), and 7-methyl-17-aza-3,7,11-triazoniabicyclo[11.3.1]heptadeca-1(17),13,15-triene 2.826-chloride 0.174-nitrate, C14H27N43+·2.826Cl−·0.174NO3−, (II), are reported. Protonation occurs at the secondary amine N atoms in (I) and at all three amine N atoms in (II) to which the Cl− ions are linked via N—H⋯Cl hydrogen bonds. The macrocyclic hole is quite different in both structures, as is observed by comparing particularly the N3⋯N4 distances [2.976 (4) and 4.175 (4) Å for (I) and (II), respectively]. In (II), a Cl− ion alternates with an NO3− ion in a disordered structure.
