Crystal structure of 3,14-diethyl-2,13-di-aza-6,17-diazo-niatri-cyclo-[16.4.0.07,12]docosane dinitrate dihydrate from synchrotron X-ray data.


ABSTRACT: The crystal structure of title salt, C22H46N4 2+·2NO3 -·2H2O, has been determined using synchrotron radiation at 220?K. The structure determination reveals that protonation has occurred at diagonally opposite amine N atoms. The asymmetric unit contains half a centrosymmetric dication, one nitrate anion and one water mol-ecule. The mol-ecular dication, C22H46N4 2+, together with the nitrate anion and hydrate water mol-ecule are involved in an extensive range of hydrogen bonds. The mol-ecule is stabilized, as is the conformation of the dication, by forming inter-molecular N-H?O, O-H?O, together with intra-molecular N-H?N hydrogen bonds.
