Nickel and palladium complexes that contain merocyanine-like 4H-imidazoles as ligands have been synthesized in good yields. The complexes were characterized by elemental analyses, mass spectrometry, 1H NMR, 13C NMR spectroscopy and in the solid state by single crystal diffraction analyses. The new palladium complexes of type 4 can be regarded as new functional dyes as well as deeply coloured and redox active metallacycles that display catalytic activity. In contrast to parent compounds 2, the palladacycles of type 4 show two well-separated reductions that are fully reversible. The values of semiquinone formation constants of derivatives 4 (between 1011 and 1012) are only somewhat lower than those reported for similar boracycles. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.
