4,7,13,18-Tetra-oxa-1,10-diazo-nia-bicyclo-[8.5.5]icosane bis-(hexa-fluorido-phosphate).

ABSTRACT: The asymmetric unit of the title structure, C(14)H(30)N(2)O(4) (2+)·2PF(6) (-), contains the anion and half of the cation, the latter being completed by a crystallographic twofold axis. The cation has a cage structure with the ammonium H atoms pointing into the cage. These H atoms are shielded from inter-molecular inter-actions and form only intra-molecular contacts. There are short inter-molecular C-H⋯F inter-actions in the structure, but no conventional inter-molecular hydrogen bonds.
