Abstract The title compound was prepared by treating a methanolic solution of 12-crown-4 with an aqueous solution of aminosulfuric acid. The crystal for X-ray analysis was obtained by recrystallization from acetone. The compound [(12-crown-4)4·[NH3SO3)6] (1) is monoclinic, space groupP21/a,a=21.900(8),b=15.499(5),c=18.079(5) Å, γ=67.85(2)°. Refinement led to a final conventionalR value of 0.0788 for 3280 reflections.
