Abstract Both title complexes were prepared by reacting a methanol solution of the respective isomer of dicyclohexano-18-crown-6 (DCH18C6) with an aqueous solution of amidosulfuric acid. Crystals suitable for X-ray crystallography were obtained by recrystallization from methanol. Crystals of [cis-syn-cis-DCH18C6][NH2SO2OH·CH3OH] (1) are monoclinic, space groupP21ln,a = 21.700(8),b = 13.725(5),c = 9.118(6) Å,ψ = 76.29(2) Å. Refinement led to a final conventionalR value of 0.065 for 2083 reflections. [Cis-anti -cis-DCH18C6][NH2SO2OH] (2) crystallizes in the orthorombic space groupPna21 with unit cell dimensionsa = 17.154(7),b = 16.051(7),c =8.630(5) Å. Refinement was terminated at anR value of 0.067 for 1936 reflections.
