The neutral complexes [((NN)-N-^)PtMes(2)], (NN)-N-^= bis(1-methyl-2-imidazolyl)ketone (bik) or N,N'-disubstituted 1,2-bis-iminoacenaphthenes (R-BIAN), Mes = mesityl, were obtained and characterized as Pt(II)species with planar N(2)PtC(2)configuration and charge transfer transitions in the visible. Reversible one-electron reduction produces radical anion complexes with the spin predominantly localized in the (NN)-N-^ ligand, according to EPR, UV/Vis-IR spectroelectrochemistry, DFT and TD-DFT studies. Reversible one-electron oxidation was also possible, attributed to the steric and electronic influence from the mesityl ligands. The EPR silent cation [(bik)PtMes(2)](+)was characterized by UV/Vis-NIR spectroscopy and TD-DFT calculations as a system with spin density contributions from Pt (31 %) and two mesityl groups (69 %).
