diffraction studies (1 and 7). The cyclic voltammograms of these complexes exhibit two reversible redox processes of [NiL2]0/1− and [NiL2]1−/2−, and one irreversible process of [NiL2]0/2+. Substituent effects on the redox properties of these complexes, in addition with those of the known complexes [Ni(o‐C6H4(NH)(NPh))2] (8) and [Ni(o‐3,5‐But2‐C6H2(NH)2)2] (9), are identified by comparing the half‐wave potentials
