摘要：

The title complex crystalizes in the centrosymmetric monoclinic space group P2(1)/n with Z = 2. The cation is the diprotonated derivative of-the neutral octadentate macrocyclic ligand C10H20N4(CH2CH2OH)4; the two protonated nitrogen atoms are as far apart as is possible in the 14-membered ring (1- and 8-positions) so as to minimize electrostatic repulsions. Each of the [C10H22N4(CH2CH2OH)(4)(2+)] cations is involved in hydrogen bonding (through the four hydroxy groups) to oxygen atoms on four different peripheral [CF3SO3-] anions.
