NiII and CuII complexes of a salen ligand bearing ferrocenes in its secondary coordination sphere† Rachel Sailer,a Warren VandeVen, b Kaeden Teindl‡a and Linus Chiang *a Abstract Herein, we report the synthesis, spectroscopic characterization and electrochemical investigation of the NiII and CuII complexes of a novel Sal ligand bearing two ferrocene moieties attached at its diimine linker, M(Sal)Fc. The electronic spectra of M(Sal)Fc are near identical to its phenyl-substituted counterpart,...
