Abstract

Several new Co(II) complexes supported by Cz^t^Bu(Pyrⁱ^Pr)₂^– ligand(s) in various ligand-to-metal ratios are reported. The synthesis and characterization of Cz^t^Bu(Pyrⁱ^Pr)₂Co (1) completes a series of analogous compounds (Cz^t^Bu(Pyrⁱ^Pr)₂M, M = Fe(II), Co(II), Ni(II)), offering insights into chemical trends across late first-row transition metal complexes. Additionally, chemical oxidation of (Cz^t^Bu(Pyrⁱ^Pr)₂)₂Co (2) gave complex 5, in which unprecedented, cobalt-facilitated C[sbnd]C coupling of pyrazole moieties has occurred.
