5. -2 M of metal perchlorate (previously dried over phosphorous pentoxide) in acetonitrile were added and the absorption spectrum recorded for each addition. K, was obtained by non-linear regression analysis.
6. Conformers are depicted similar to those predicted by AMI calculations as the most stable ones.
