potentially penta-coordinating ligand L1 has been synthesized by reaction of the bridge bis-(2-(methylsulfonyl)oxyethyl)ether with the tetraazamacrocycle cyclam (cyclam = 1,4,8,11-tetraazatetradecane). The copper(II) complex was characterized initially and subsequent demetallation provided pure L1. Electrochemical and chemical oxidation of the nickel(II) species yields a Ni(III) ion (low-spin d7, rhombic, gxx
