The asymmetric unit of the title compound C(20)H(30)N(4)S(2) (+). 2ClO(4) (-) comprises one macrocyclic cation and two perchlorate anions. In the cation, one of the protonated H atoms bound to the amide N atom is involved in an intra-molecular N-H⋯N hydrogen bond. The O atoms in the two perchlorate anions are disordered over two sets of sites with occupancy ratios of 0.65 (3):0.35 (3) and 0.640 (15):0.360 (15). ...[more]
