Ammonium hexa-fluorido-phosphate-18-crown-6 (1/1).


ABSTRACT: In the crystal structure of the title compound, NH(4) (+)·PF(6) (-)·C(12)H(24)O(6), the cation is situated in the 18-crown-6 ring, forming a supra-molecular rotator-stator-like structure held by N-H?O hydrogen bonds. The six O atoms of the crown ether lie approximately in a plane [mean deviation 0.2129?(3)?Å]; the N atom is displaced by 0.864?(3)Å from the centroid of the 18-crown-6 ring. The slightly distorted tetra-hedral cations further inter-act with the slightly distorted octa-hedral anions via inter-molecular N-H?F hydrogen bonds.
