In addition to perchlorate adducts, this study showed that the copper(II) tetrathiaether macrocyclic complexes also formed adducts with other potentially noncomplexing anions such as tetrafluoroborate and trifluoromethylsulfonate (triflate).

As noted in refs 12, 23, and 24, the five conformers are defined according to the orientations of the amine hydrogens or the sulfur lone-pair electrons relative to the donor atom plane as follows (where + represents above the plane, - is below the plane, and the order of the donor atoms is 1, 4, 8, and 11): conformer I, + + + +; conformer II, + + + -; conformer III, + - - +; conformer IV, + + - -; conformer V, + - + -.

29. II(L10) complex is the only definitive example in the literature of a crystal structure for a divalent metal complex involving a quadridentate macrocyclic ligand for which the ligand is in conformer II. Conformer II has also been indicated for the blue form of copper-(II) (C-meso-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane), but the crystal structure was not satisfactorily resolved: Clay, R.; Murray-Rust, J.; Murray-Rust, P.

Although the overall energies are not reliable using this approach, the relative residuals should reflect the differences in the overall internal ligand strain in the various conformers because all other factors are reasonably equivalent for each conformer.
