Abstract
Macrotetracyclic complexes of nickel(II) containing crown ethers as pendant arms, [Ni(B)](ClO4)(2) and [Ni(C)](ClO4)(2), were prepared and characteriz ed. The binding constants of the complexes toward alkali metal ions are rel atively small compared with those of free 15-crown-5 or 18-crown-6 and the reduction potentials of the [Ni(B)](ClO4)(2) and [Ni(C)](ClO4)(2) in the pr esence of alkali metal ions shift to the positive direction in the order Li +>Na+>K+ and K+>Na+>Li+, respectively.
