Crystal structure of 1,4,8,11-tetra­methyl-1,4,8,11-tetra­azonia­cyclo­tetra­decane bis­(perchlorate) dichloride from synchrotron X-ray data

The crystal structure of title salt, C(14)H(36)N(4) (4+)·2ClO(4) (−)·2Cl(−), has been determined using synchrotron radiation at 220 K. The structure determination reveals that protonation has occurred at all four amine N atoms. The asymmetric unit contains one half-cation (completed by crystallographic inversion symmetry), one perchlorate anion and one chloride anion. A distortion of the perchlorate anion is due to its involvement in hydrogen-bonding inter­actions with the cations. The crystal structure is consolidated by inter­molecular hydrogen bonds involving the 1,4,8,11-tetra­methyl-1,4,8,11-tetra­azonia­cyclo­tetra­decane N—H and C—H groups as donor groups, and the O atoms of the perchlorate and chloride anion as acceptor groups, giving rise to a three-dimensional network.
