meso-5,5,7,12,12,14-Hexamethyl-1,4,8,11-tetraazacyclotetradecane Dihydroperchlorate Monohydrate

The crystal structure of the title compound meso-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane-4,11-diium diperchlorate monohydrate, C₁₆H₃₈N₄²⁺.2ClO₄^-.H₂O, has been determined. The cationic ring contains two protonated and two secondary amine N atoms. The protonated N atoms display one long and one short N-C bond, with values of 1.526 (4) and 1.484 (4) Å, respectively. Similarly, the secondary amine N atoms also display one long and one short N-C bond, with values of 1.485 (4) and 1.455 (4) Å, respectively. A rather complicated hydrogen-bonding space system is present in the crystal.
