Abstract
The diprotonated (H2TETP)(2-) macrocycle in the title compound, 2Na(+) .C22H38N4O82-.16H(2)O Or 2Na(+). (H2TETP)(2-).16H(2)O, possesses a [34 34] conformation, the propionate arms all being deprotonated. Two are extended and the other two are folded towards two protonated N atoms. The crystal structure is stabilized by a complex hydrogen-bonding sche me since the unit cell contains 16 water molecules.
