New Pyridine-modified Macrocycle and Its Ability to Encapsulate Four Divalent Metal Ions [Nickel(II), Manganese(II), and Zinc(II)] into the Ring
A large phenol- and polyether chain-based macrocycle H<SUB>2</SUB>L<SUB>py</SUB> possessing four pyridylmethyl groups as pendant donors was prepared and its ability to encapsulate four divalent metal ions [Ni(II), Mn(II), and Zn(II)] was confirmed by IR and NMR spectroscopy and X-ray crystallography.
