摘要
In the crystal structure of the title compound, NH(4) +center dot PF(6) -center dot C(12)H(24)O(6), the cation is situated in the 18-crown-6 ring, forming a supramolecular 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) A]; the N atom is displaced by 0.864 (3)A from the centroid of the 18-crown-6 ring. The slightly distorted tetrahedral cations further interact with the slightly distorted octahedral anions via intermolecular N-H...F hydrogen bonds.
