Two new series of cobaloxime complexes of formulae [Co(Hdmg)₂{(CH₂)_n I}(py)] (Hdmg = the monoanion of dimethylglyoxime, py = pyridine and n = 5, 6, 8, 9 or 10) and [Co(Hdmg)₂{(CH₂)₃OC(O)C₆H₄R}(py)] (R = H, o-, m-or p-OCH₃, p-OC₇H₁₅ or p-OC₉H₁₉) have been synthesized and fully characterized. The former series provides versatile precursor species for a wide range of polymethylene homo-and heteronuclear complexes, while the latter series confirms that, under mild conditions, elaboration from an ω-hydroxyl group can be achieved to generate stable metal complexes.
