beta-meso-(5,7,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane)nickel(II) diperchlorate monohydrate

摘要

[[abstract]]In the title compound, [Ni(C16H36N4)](ClO4)(2).H2O, the Ni-II ion is four-coordinated by the four N atoms of the macrocyclic ligand. The four N atoms are coplanar to within 0.05 Angstrom and the four H atoms attached to the N atoms are located on the same side of the macrocyclic plane. The configuration of the four chiral nitrogen centres and two chiral carbon centres are (1RS,4SR,8RS,11SR) and (5SR,14RS), respectively. The two five-membered chelate rings are in unstable eclipsed forms and the two six-membered chelate rings are in stable chair forms. The two methyl groups attached to the asymmetric C atoms are equatorial. The perchlorate ions and water O atom are not within the bonding distance of the cation.
